* Add 00git_inet_cidr_unpack.patch: Revert the behavior of inet/cidr
  functions to not unpack the arguments. This fixes the memory leak when
  sorting inet values. Patch taken from upstream git HEAD. Spotted during
  testing in LP #904631.
* 01-armel-tas.patch: Turn slock_t datatype into an int, and define
  S_UNLOCK() to call __sync_lock_release() instead of using the default
  implementation. This complies to the gcc built-in atomic operations
  specifiction more strictly and now also works on the Panda boards.
  (LP: #904828)

* New upstream release (LP: #904631)
  - Fix bugs in information_schema.referential_constraints view.
    This view was being insufficiently careful about matching the
    foreign-key constraint to the depended-on primary or unique key
    constraint. That could result in failure to show a foreign key
    constraint at all, or showing it multiple times, or claiming that
    it depends on a different constraint than the one it really does.
    Since the view definition is installed by initdb, merely upgrading
    will not fix the problem. If you need to fix this in an existing
    installation, you can (as a superuser) drop the information_schema
    schema then re-create it by sourcing
    "SHAREDIR/information_schema.sql". (Run pg_config --sharedir if
    you're uncertain where "SHAREDIR" is.) This must be repeated in
    each database to be fixed.
  - Fix incorrect replay of WAL records for GIN index updates.
    This could result in transiently failing to find index entries
    after a crash, or on a hot-standby server. The problem would be
    repaired by the next "VACUUM" of the index, however.
  - Fix TOAST-related data corruption during CREATE TABLE dest AS
    SELECT - FROM src or INSERT INTO dest SELECT * FROM src.
    If a table has been modified by "ALTER TABLE ADD COLUMN", attempts
    to copy its data verbatim to another table could produce corrupt
    results in certain corner cases. The problem can only manifest in
    this precise form in 8.4 and later, but we patched earlier versions
    as well in case there are other code paths that could trigger the
    same bug.
  - Fix race condition during toast table access from stale syscache
    entries.
  - Track dependencies of functions on items used in parameter default
    expressions. Previously, a referenced object could be dropped without
    having dropped or modified the function, leading to misbehavior when the
    function was used. Note that merely installing this update will not fix
    the missing dependency entries; to do that, you'd need to "CREATE OR
    REPLACE" each such function afterwards. If you have functions whose
    defaults depend on non-built-in objects, doing so is recommended.
  - Allow inlining of set-returning SQL functions with multiple OUT
    parameters.
  - Make DatumGetInetP() unpack inet datums that have a 1-byte header,
    and add a new macro, DatumGetInetPP(), that does not.
  - Improve locale support in money type's input and output.
    Aside from not supporting all standard lc_monetary formatting
    options, the input and output functions were inconsistent, meaning
    there were locales in which dumped money values could not be
    re-read.
  - Don't let transform_null_equals affect CASE foo WHEN NULL ...
    constructs. transform_null_equals is only supposed to affect foo = NULL
    expressions written directly by the user, not equality checks
    generated internally by this form of CASE.
  - Change foreign-key trigger creation order to better support
    self-referential foreign keys. For a cascading foreign key that
    references its own table, a row update will fire both the ON UPDATE
    trigger and the CHECK trigger as one event. The ON UPDATE trigger must
    execute first, else the CHECK will check a non-final state of the row
    and possibly throw an inappropriate error. However, the firing order of
    these triggers is determined by their names, which generally sort in
    creation order since the triggers have auto-generated names following
    the convention "RI_ConstraintTrigger_NNNN". A proper fix would require
    modifying that convention, which we will do in 9.2, but it seems risky
    to change it in existing releases. So this patch just changes the
    creation order of the triggers. Users encountering this type of error
    should drop and re-create the foreign key constraint to get its triggers
    into the right order.
  - Avoid floating-point underflow while tracking buffer allocation
    rate.
  - Preserve blank lines within commands in psql's command history.
    The former behavior could cause problems if an empty line was
    removed from within a string literal, for example.
  - Fix pg_dump to dump user-defined casts between auto-generated
    types, such as table rowtypes.
  - Use the preferred version of xsubpp to build PL/Perl, not
    necessarily the operating system's main copy.
  - Fix incorrect coding in "contrib/dict_int" and "contrib/dict_xsyn".
  - Honor query cancel interrupts promptly in pgstatindex().
  - Ensure VPATH builds properly install all server header files.
  - Shorten file names reported in verbose error messages.
    Regular builds have always reported just the name of the C file
    containing the error message call, but VPATH builds formerly
    reported an absolute path name.

* New upstream bug fix release: (LP: #767165)
  - If your installation was upgraded from a previous major release by
    running pg_upgrade, you should take action to prevent possible data loss
    due to a now-fixed bug in pg_upgrade. The recommended solution is to run
    "VACUUM FREEZE" on all TOAST tables. More information is available at
    http://wiki.postgresql.org/wiki/20110408pg_upgrade_fix.
  - Fix pg_upgrade's handling of TOAST tables.
    This error poses a significant risk of data loss for installations
    that have been upgraded with pg_upgrade. This patch corrects the
    problem for future uses of pg_upgrade, but does not in itself cure
    the issue in installations that have been processed with a buggy
    version of pg_upgrade.
  - Suppress incorrect "PD_ALL_VISIBLE flag was incorrectly set"
    warning.
  - Disallow including a composite type in itself.
  - Avoid potential deadlock during catalog cache initialization.
  - Fix dangling-pointer problem in BEFORE ROW UPDATE trigger handling
    when there was a concurrent update to the target tuple.
  - Disallow "DROP TABLE" when there are pending deferred trigger
    events for the table.
    Formerly the "DROP" would go through, leading to "could not open
    relation with OID nnn" errors when the triggers were eventually
    fired.
  - Prevent crash triggered by constant-false WHERE conditions during
    GEQO optimization.
  - Improve planner's handling of semi-join and anti-join cases.
  - Fix selectivity estimation for text search to account for NULLs.
  - Improve PL/pgSQL's ability to handle row types with dropped columns.
  - Fix PL/Python memory leak involving array slices.
  - Fix pg_restore to cope with long lines (over 1KB) in TOC files.
  - Put in more safeguards against crashing due to division-by-zero
    with overly enthusiastic compiler optimization. (Closes: #616180)

15. By Martin Pitt on 2010-12-21

* New upstream bug fix release: (LP: #693157)
  - Force the default wal_sync_method to be fdatasync on Linux.
    The default on Linux has actually been fdatasync for many years,
    but recent kernel changes caused PostgreSQL to choose open_datasync
    instead. This choice did not result in any performance improvement,
    and caused outright failures on certain filesystems, notably ext4
    with the data=journal mount option.
  - Fix assorted bugs in WAL replay logic for GIN indexes.
    This could result in "bad buffer id: 0" failures or corruption of
    index contents during replication.
  - Fix recovery from base backup when the starting checkpoint WAL
    record is not in the same WAL segment as its redo point.
  - Fix persistent slowdown of autovacuum workers when multiple workers
    remain active for a long time.
    The effective vacuum_cost_limit for an autovacuum worker could drop
    to nearly zero if it processed enough tables, causing it to run
    extremely slowly.
  - Add support for detecting register-stack overrun on IA64.
    The IA64 architecture has two hardware stacks. Full prevention of
    stack-overrun failures requires checking both.
  - Add a check for stack overflow in copyObject().
    Certain code paths could crash due to stack overflow given a
    sufficiently complex query.
  - Fix detection of page splits in temporary GiST indexes.
    It is possible to have a "concurrent" page split in a temporary
    index, if for example there is an open cursor scanning the index
    when an insertion is done. GiST failed to detect this case and
    hence could deliver wrong results when execution of the cursor
    continued.
  - Fix error checking during early connection processing.
    The check for too many child processes was skipped in some cases,
    possibly leading to postmaster crash when attempting to add the new
    child process to fixed-size arrays.
  - Improve efficiency of window functions.
    Certain cases where a large number of tuples needed to be read in
    advance, but work_mem was large enough to allow them all to be held
    in memory, were unexpectedly slow. percent_rank(), cume_dist() and
    ntile() in particular were subject to this problem.
  - Avoid memory leakage while "ANALYZE"'ing complex index expressions.
  - Ensure an index that uses a whole-row Var still depends on its
    table.
    An index declared like create index i on t (foo(t.-)) would not
    automatically get dropped when its table was dropped.
  - Do not "inline" a SQL function with multiple OUT parameters.
    This avoids a possible crash due to loss of information about the
    expected result rowtype.
  - Behave correctly if ORDER BY, LIMIT, FOR UPDATE, or WITH is
    attached to the VALUES part of INSERT ... VALUES.
  - Fix constant-folding of COALESCE() expressions.
    The planner would sometimes attempt to evaluate sub-expressions
    that in fact could never be reached, possibly leading to unexpected
    errors.
  - Fix postmaster crash when connection acceptance (accept() or one of
    the calls made immediately after it) fails, and the postmaster was
    compiled with GSSAPI support.
  - Fix missed unlink of temporary files when log_temp_files is active.
    If an error occurred while attempting to emit the log message, the
    unlink was not done, resulting in accumulation of temp files.
  - Add print functionality for InhRelation nodes.
    This avoids a failure when debug_print_parse is enabled and certain
    types of query are executed.
  - Fix incorrect calculation of distance from a point to a horizontal
    line segment.
    This bug affected several different geometric distance-measurement
    operators.
  - Fix incorrect calculation of transaction status in ecpg.
  - Fix PL/pgSQL's handling of "simple" expressions to not fail in
    recursion or error-recovery cases.
  - Fix PL/Python's handling of set-returning functions.
    Attempts to call SPI functions within the iterator generating a set
    result would fail.
  - Fix bug in "contrib/cube"'s GiST picksplit algorithm.
    This could result in considerable inefficiency, though not actually
    incorrect answers, in a GiST index on a cube column. If you have
    such an index, consider "REINDEX"ing it after installing this
    update.
  - Don't emit "identifier will be truncated" notices in
    "contrib/dblink" except when creating new connections.
  - Fix potential coredump on missing public key in "contrib/pgcrypto".
  - Fix memory leak in "contrib/xml2"'s XPath query functions.

* New upstream security/bug fix update: (LP: #655293)
  - Use a separate interpreter for each calling SQL userid in PL/Perl
    and PL/Tcl.
    This change prevents security problems that can be caused by
    subverting Perl or Tcl code that will be executed later in the same
    session under another SQL user identity (for example, within a
    SECURITY DEFINER function). Most scripting languages offer numerous
    ways that that might be done, such as redefining standard functions
    or operators called by the target function. Without this change,
    any SQL user with Perl or Tcl language usage rights can do
    essentially anything with the SQL privileges of the target
    function's owner.
    The cost of this change is that intentional communication among
    Perl and Tcl functions becomes more difficult. To provide an escape
    hatch, PL/PerlU and PL/TclU functions continue to use only one
    interpreter per session. This is not considered a security issue
    since all such functions execute at the trust level of a database
    superuser already.
    It is likely that third-party procedural languages that claim to
    offer trusted execution have similar security issues. We advise
    contacting the authors of any PL you are depending on for
    security-critical purposes.
    Our thanks to Tim Bunce for pointing out this issue
    (CVE-2010-3433).
  - Prevent possible crashes in pg_get_expr() by disallowing it from
    being called with an argument that is not one of the system catalog
    columns it's intended to be used with.
  - Fix incorrect placement of placeholder evaluation.
    This bug could result in query outputs being non-null when they
    should be null, in cases where the inner side of an outer join is a
    sub-select with non-strict expressions in its output list.
  - Fix possible duplicate scans of UNION ALL member relations.
  - Fix "cannot handle unplanned sub-select" error.
    This occurred when a sub-select contains a join alias reference
    that expands into an expression containing another sub-select.
  - Fix mishandling of whole-row Vars that reference a view or
    sub-select and appear within a nested sub-select.
  - Fix mishandling of cross-type IN comparisons.
    This could result in failures if the planner tried to implement an
    IN join with a sort-then-unique-then-plain-join plan.
  - Fix computation of "ANALYZE" statistics for tsvector columns.
    The original coding could produce incorrect statistics, leading to
    poor plan choices later.
  - Improve planner's estimate of memory used by array_agg(),
    string_agg(), and similar aggregate functions.
    The previous drastic underestimate could lead to out-of-memory
    failures due to inappropriate choice of a hash-aggregation plan.
  - Fix failure to mark cached plans as transient.
    If a plan is prepared while "CREATE INDEX CONCURRENTLY" is in
    progress for one of the referenced tables, it is supposed to be
    re-planned once the index is ready for use. This was not happening
    reliably.
  - Reduce PANIC to ERROR in some occasionally-reported btree failure
    cases, and provide additional detail in the resulting error
    messages.
    This should improve the system's robustness with corrupted indexes.
  - Fix incorrect search logic for partial-match queries with GIN
    indexes.
    Cases involving AND/OR combination of several GIN index conditions
    didn't always give the right answer, and were sometimes much slower
    than necessary.
  - Prevent show_session_authorization() from crashing within
    autovacuum processes.
  - Defend against functions returning setof record where not all the
    returned rows are actually of the same rowtype.
  - Fix possible corruption of pending trigger event lists during
    subtransaction rollback.
    This could lead to a crash or incorrect firing of triggers.
  - Fix possible failure when hashing a pass-by-reference function
    result.
  - Improve merge join's handling of NULLs in the join columns.
    A merge join can now stop entirely upon reaching the first NULL, if
    the sort order is such that NULLs sort high.
  - Take care to fsync the contents of lockfiles (both "postmaster.pid"
    and the socket lockfile) while writing them.
    This omission could result in corrupted lockfile contents if the
    machine crashes shortly after postmaster start. That could in turn
    prevent subsequent attempts to start the postmaster from
    succeeding, until the lockfile is manually removed.
  - Avoid recursion while assigning XIDs to heavily-nested
    subtransactions.
    The original coding could result in a crash if there was limited
    stack space.
  - Avoid holding open old WAL segments in the walwriter process.
    The previous coding would prevent removal of no-longer-needed
    segments.
  - Fix log_line_prefix's %i escape, which could produce junk early in
    backend startup.
  - Prevent misinterpretation of partially-specified relation options
    for TOAST tables.
    In particular, fillfactor would be read as zero if any other
    reloption had been set for the table, leading to serious bloat.
  - Fix inheritance count tracking in "ALTER TABLE ... ADD CONSTRAINT"
  - Fix possible data corruption in "ALTER TABLE ... SET TABLESPACE"
    when archiving is enabled.
  - Allow "CREATE DATABASE" and "ALTER DATABASE ... SET TABLESPACE" to
    be interrupted by query-cancel.
  - Improve "CREATE INDEX"'s checking of whether proposed index
    expressions are immutable.
  - Fix "REASSIGN OWNED" to handle operator classes and families.
  - Fix possible core dump when comparing two empty tsquery values.
  - Fix LIKE's handling of patterns containing % followed by _.
    We've fixed this before, but there were still some
    incorrectly-handled cases.
  - Re-allow input of Julian dates prior to 0001-01-01 AD.
    Input such as 'J100000'::date worked before 8.4, but was
    unintentionally broken by added error-checking.
  - Fix PL/pgSQL to throw an error, not crash, if a cursor is closed
    within a FOR loop that is iterating over that cursor.
  - In PL/Python, defend against null pointer results from
    PyCObject_AsVoidPtr and PyCObject_FromVoidPtr.
  - In libpq, fix full SSL certificate verification for the case where
    both host and hostaddr are specified.
  - Make psql recognize "DISCARD ALL" as a command that should not be
    encased in a transaction block in autocommit-off mode.
  - Fix some issues in pg_dump's handling of SQL/MED objects.
    Notably, pg_dump would always fail if run by a non-superuser, which
    was not intended.
  - Improve pg_dump and pg_restore's handling of non-seekable archive
    files.
    This is important for proper functioning of parallel restore.
  - Improve parallel pg_restore's ability to cope with selective
    restore (-L option).
    The original code tended to fail if the -L file commanded a
    non-default restore ordering.
  - Fix ecpg to process data from RETURNING clauses correctly.
  - Fix some memory leaks in ecpg.
  - Improve "contrib/dblink"'s handling of tables containing dropped
    columns.
  - Fix connection leak after "duplicate connection name" errors in
    "contrib/dblink".
  - Fix "contrib/dblink" to handle connection names longer than 62
    bytes correctly.
  - Add hstore(text, text) function to "contrib/hstore".
    This function is the recommended substitute for the now-deprecated
    => operator. It was back-patched so that future-proofed code can be
    used with older server versions. Note that the patch will be
    effective only after "contrib/hstore" is installed or reinstalled
    in a particular database. Users might prefer to execute the "CREATE
    FUNCTION" command by hand, instead.
  - Update build infrastructure and documentation to reflect the source
    code repository's move from CVS to Git.
* debian/postgresql-8.4.preinst: Add missing debhelper token.
* debian/control: Bump Standards-Version to 3.9.1 (no changes necessary).

13. By Martin Pitt on 2010-07-19

* Migrate to a common init script for all server versions, to avoid
  providing the "postgresql" service in multiple packages (which causes
  insserv to complain bitterly):
  - Drop debian/postgresql-8.4.init.
  - debian/control: Bump dependency to postgresql-common to ensure we have a
    common /etc/init.d/postgresql init script.
  - debian/postgresql-8.4.preinst: Remove/rename our init script on upgrade.
  - debian/postgresql-8.4.prerm: Call stop_version on upgrade.
  - debian/rules: Drop dh_installinit arguments.
  - (Closes: #585890)

12. By Martin Pitt on 2010-05-15

* Urgency medium due to security fixes.
* New upstream security/bug fix release:
  - Enforce restrictions in plperl using an opmask applied to the whole
    interpreter, instead of using "Safe.pm".
    Recent developments have convinced us that "Safe.pm" is too
    insecure to rely on for making plperl trustable. This change
    removes use of "Safe.pm" altogether, in favor of using a separate
    interpreter with an opcode mask that is always applied. Pleasant
    side effects of the change include that it is now possible to use
    Perl's strict pragma in a natural way in plperl, and that Perl's $a
    and $b variables work as expected in sort routines, and that
    function compilation is significantly faster. (CVE-2010-1169)
  - Prevent PL/Tcl from executing untrustworthy code from pltcl_modules.
    PL/Tcl's feature for autoloading Tcl code from a database table
    could be exploited for trojan-horse attacks, because there was no
    restriction on who could create or insert into that table. This
    change disables the feature unless pltcl_modules is owned by a
    superuser. (However, the permissions on the table are not checked,
    so installations that really need a less-than-secure modules table
    can still grant suitable privileges to trusted non-superusers.)
    Also, prevent loading code into the unrestricted "normal" Tcl
    interpreter unless we are really going to execute a pltclu
    function. (CVE-2010-1170)
  - Fix data corruption during WAL replay of ALTER ... SET TABLESPACE.
    When archive_mode is on, ALTER ... SET TABLESPACE generates a WAL
    record whose replay logic was incorrect. It could write the data to
    the wrong place, leading to possibly-unrecoverable data corruption.
    Data corruption would be observed on standby slaves, and could
    occur on the master as well if a database crash and recovery
    occurred after committing the ALTER and before the next checkpoint.
  - Fix possible crash if a cache reset message is received during
    rebuild of a relcache entry.
    This error was introduced in 8.4.3 while fixing a related failure.
  - Apply per-function GUC settings while running the language
    validator for the function. This avoids failures if the function's code
    is invalid without the setting; an example is that SQL functions may not
    parse if the search_path is not correct.
  - Do constraint exclusion for inherited "UPDATE" and "DELETE" target
    tables when constraint_exclusion = partition.
    Due to an oversight, this setting previously only caused constraint
    exclusion to be checked in "SELECT" commands.
  - Do not allow an unprivileged user to reset superuser-only parameter
    settings.
    Previously, if an unprivileged user ran ALTER USER ... RESET ALL
    for himself, or ALTER DATABASE ... RESET ALL for a database he
    owns, this would remove all special parameter settings for the user
    or database, even ones that are only supposed to be changeable by a
    superuser. Now, the "ALTER" will only remove the parameters that
    the user has permission to change.
  - Avoid possible crash during backend shutdown if shutdown occurs
    when a CONTEXT addition would be made to log entries.
    In some cases the context-printing function would fail because the
    current transaction had already been rolled back when it came time
    to print a log message.
  - Fix erroneous handling of %r parameter in recovery_end_command.
    The value always came out zero.
  - Ensure the archiver process responds to changes in archive_command
    as soon as possible.
  - Fix pl/pgsql's CASE statement to not fail when the case expression
    is a query that returns no rows.
  - Update pl/perl's "ppport.h" for modern Perl versions.
  - Fix assorted memory leaks in pl/python.
  - Handle empty-string connect parameters properly in ecpg.
  - Prevent infinite recursion in psql when expanding a variable that
    refers to itself.
  - Fix psql's \copy to not add spaces around a dot within \copy
    (select ...).
    Addition of spaces around the decimal point in a numeric literal
    would result in a syntax error.
  - Avoid formatting failure in psql when running in a locale context
    that doesn't match the client_encoding.
  - Fix unnecessary "GIN indexes do not support whole-index scans"
    errors for unsatisfiable queries using "contrib/intarray" operators.
  - Ensure that "contrib/pgstattuple" functions respond to cancel
    interrupts promptly.

11. By Martin Pitt on 2010-03-13

* New upstream bug fix release:
  - Add new configuration parameter ssl_renegotiation_limit to control
    how often we do session key renegotiation for an SSL connection.
    This can be set to zero to disable renegotiation completely, which
    may be required if a broken SSL library is used. In particular,
    some vendors are shipping stopgap patches for CVE-2009-3555 that
    cause renegotiation attempts to fail.
  - Fix possible deadlock during backend startup.
  - Fix possible crashes due to not handling errors during relcache
    reload cleanly.
  - Fix possible crash due to use of dangling pointer to a cached plan.
  - Fix possible crash due to overenthusiastic invalidation of cached
    plan for "ROLLBACK".
  - Fix possible crashes when trying to recover from a failure in
    subtransaction start.
  - Fix server memory leak associated with use of savepoints and a
    client encoding different from server's encoding.
  - Fix incorrect WAL data emitted during end-of-recovery cleanup of a
    GIST index page split.
  - Fix bug in WAL redo cleanup method for GIN indexes.
  - Fix incorrect comparison of scan key in GIN index search.
  - Make substring() for bit types treat any negative length as meaning
    "all the rest of the string". The previous coding treated only -1 that
    way, and would produce an invalid result value for other negative
    values, possibly leading to a crash (CVE-2010-0442).
  - Fix integer-to-bit-string conversions to handle the first
    fractional byte correctly when the output bit width is wider than
    the given integer by something other than a multiple of 8 bits.
  - Fix some cases of pathologically slow regular expression matching.
  - Fix bug occurring when trying to inline a SQL function that returns
    a set of a composite type that contains dropped columns.
  - Fix bug with trying to update a field of an element of a
    composite-type array column.
  - Avoid failure when "EXPLAIN" has to print a FieldStore or
    assignment ArrayRef expression.
    These cases can arise now that "EXPLAIN VERBOSE" tries to print
    plan node target lists.
  - Avoid an unnecessary coercion failure in some cases where an
    undecorated literal string appears in a subquery within
    "UNION"/"INTERSECT"/"EXCEPT".
    This fixes a regression for some cases that worked before 8.4.
  - Avoid undesirable rowtype compatibility check failures in some
    cases where a whole-row Var has a rowtype that contains dropped
    columns.
  - Fix the STOP WAL LOCATION entry in backup history files to report
    the next WAL segment's name when the end location is exactly at a
    segment boundary.
  - Always pass the catalog ID to an option validator function
    specified in "CREATE FOREIGN DATA WRAPPER".
  - Fix some more cases of temporary-file leakage.
    This corrects a problem introduced in the previous minor release.
    One case that failed is when a plpgsql function returning set is
    called within another function's exception handler.
  - Add support for doing FULL JOIN ON FALSE.
    This prevents a regression from pre-8.4 releases for some queries
    that can now be simplified to a constant-false join condition.
  - Improve constraint exclusion processing of boolean-variable cases,
    in particular make it possible to exclude a partition that has a
    "bool_column = false" constraint.
  - Prevent treating an INOUT cast as representing binary compatibility.
  - Include column name in the message when warning about inability to
    grant or revoke column-level privileges.
    This is more useful than before and helps to prevent confusion when
    a "REVOKE" generates multiple messages, which formerly appeared to
    be duplicates.
  - When reading "pg_hba.conf" and related files, do not treat
    @something as a file inclusion request if the @ appears inside
    quote marks; also, never treat @ by itself as a file inclusion
    request.
    This prevents erratic behavior if a role or database name starts
    with @. If you need to include a file whose path name contains
    spaces, you can still do so, but you must write @"/path to/file"
    rather than putting the quotes around the whole construct.
  - Prevent infinite loop on some platforms if a directory is named as
    an inclusion target in "pg_hba.conf" and related files.
  - Fix possible infinite loop if SSL_read or SSL_write fails without
    setting errno.
    This is reportedly possible with some Windows versions of openssl.
  - Disallow GSSAPI authentication on local connections, since it
    requires a hostname to function correctly.
  - Protect ecpg against applications freeing strings unexpectedly.
  - Make ecpg report the proper SQLSTATE if the connection disappears.
  - Fix translation of cell contents in psql \d output.
  - Fix psql's numericlocale option to not format strings it shouldn't
    in latex and troff output formats.
  - Fix a small per-query memory leak in psql.
  - Make psql return the correct exit status (3) when ON_ERROR_STOP and
    --single-transaction are both specified and an error occurs during
    the implied "COMMIT".
  - Fix pg_dump's output of permissions for foreign servers.
  - Fix possible crash in parallel pg_restore due to out-of-range
    dependency IDs.
  - Fix plpgsql failure in one case where a composite column is set to
    NULL.
  - Fix possible failure when calling PL/Perl functions from PL/PerlU
    or vice versa.
  - Add volatile markings in PL/Python to avoid possible
    compiler-specific misbehavior>
  - Ensure PL/Tcl initializes the Tcl interpreter.
    The only known symptom of this oversight is that the Tcl clock
    command misbehaves if using Tcl 8.5 or later.
  - Prevent ExecutorEnd from being run on portals created within a
    failed transaction or subtransaction.
    This is known to cause issues when using "contrib/auto_explain".
  - Prevent crash in "contrib/dblink" when too many key columns are
    specified to a dblink_build_sql_- function.
  - Allow zero-dimensional arrays in "contrib/ltree" operations.
    This case was formerly rejected as an error, but it's more
    convenient to treat it the same as a zero-element array. In
    particular this avoids unnecessary failures when an ltree operation
    is applied to the result of ARRAY(SELECT ...) and the sub-select
    returns no rows.
  - Fix assorted crashes in "contrib/xml2" caused by sloppy memory
    management.

* Add 04-armel-tas.patch: Fix ftbfs on armel: Use gcc intrinsics rather
  than assembler to implement tas (test and set). (LP: #497331)

[ Martin Pitt ]
* Drop 15-dict-fallback-dir.patch: p-common 104 now directly creates the
  names tsearch is looking for. Bump p-common dependency accordingly.
