postgresql-9.0 9.0.4-1 source package in Ubuntu

Changelog

postgresql-9.0 (9.0.4-1) unstable; urgency=medium

  Priority medium due to data-loss pg_upgrade bug.

  * New upstream bug fix release:
    - 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.
    - Use better SQLSTATE error codes for hot standby conflict cases.
    - Prevent intermittent hang in interactions of startup process with
      bgwriter process.  This affected recovery in non-hot-standby cases.
    - 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.
    - Allow "replication" as a user name in "pg_hba.conf".
      "replication" is special in the database name column, but it was
      mistakenly also treated as special in the user name column.
    - Prevent crash triggered by constant-false WHERE conditions during
      GEQO optimization.
    - Improve planner's handling of semi-join and anti-join cases.
    - Fix handling of SELECT FOR UPDATE in a sub-SELECT.
      This bug typically led to "cannot extract system attribute from
      virtual tuple" errors.
    - Fix selectivity estimation for text search to account for NULLs.
    - Fix get_actual_variable_range() to support hypothetical indexes
      injected by an index adviser plugin.
    - Fix PL/Python memory leak involving array slices.
    - Allow libpq's SSL initialization to succeed when user's home
      directory is unavailable.
      If the SSL mode is such that a root certificate file is not
      required, there is no need to fail. This change restores the
      behavior to what it was in pre-9.0 releases.
    - Fix libpq to return a useful error message for errors detected in
      conninfo_array_parse.
    - Fix ecpg preprocessor's handling of float constants.
    - Fix parallel pg_restore to handle comments on POST_DATA items
      correctly.
    - 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)
  * debian/control: Build debug package. (Closes: #551880)
  * debian/control, debian/rules: Drop usage of pycentral. We don't ship any
    Python extension/module, so we don't need a python helper at all.
    (Closes: #616949)

postgresql-9.0 (9.0.3-1) unstable; urgency=low

  * New upstream security/bug fix release:
    - Fix buffer overrun in "contrib/intarray"'s input function for the
      query_int type.
      This bug is a security risk since the function's return address
      could be overwritten. Thanks to Apple Inc's security team for
      reporting this issue and supplying the fix. (CVE-2010-4015)
    - Before exiting walreceiver, ensure all the received WAL is fsync'd
      to disk. Otherwise the standby server could replay some un-synced WAL,
      conceivably leading to data corruption if the system crashes just
      at that point.
    - Avoid excess fsync activity in walreceiver.
    - Make "ALTER TABLE" revalidate uniqueness and exclusion constraints
      when needed. This was broken in 9.0 by a change that was intended to
      suppress revalidation during "VACUUM FULL" and "CLUSTER", but
      unintentionally affected "ALTER TABLE" as well.
    - Fix EvalPlanQual for "UPDATE" of an inheritance tree in which the
      tables are not all alike.
      Any variation in the table row types (including dropped columns
      present in only some child tables) would confuse the EvalPlanQual
      code, leading to misbehavior or even crashes. Since EvalPlanQual is
      only executed during concurrent updates to the same row, the
      problem was only seen intermittently.
    - Avoid failures when "EXPLAIN" tries to display a simple-form CASE
      expression.
      If the CASE's test expression was a constant, the planner could
      simplify the CASE into a form that confused the expression-display
      code, resulting in "unexpected CASE WHEN clause" errors.
    - Fix assignment to an array slice that is before the existing range
      of subscripts.
      If there was a gap between the newly added subscripts and the first
      pre-existing subscript, the code miscalculated how many entries
      needed to be copied from the old array's null bitmap, potentially
      leading to data corruption or crash.
    - Avoid unexpected conversion overflow in planner for very distant
      date values.
      The date type supports a wider range of dates than can be
      represented by the timestamp types, but the planner assumed it
      could always convert a date to timestamp with impunity.
    - Fix PL/Python crash when an array contains null entries.
    - Remove ecpg's fixed length limit for constants defining an array
      dimension.
    - Fix erroneous parsing of tsquery values containing ... &
      !(subexpression) | ... .
      Queries containing this combination of operators were not executed
      correctly. The same error existed in "contrib/intarray"'s query_int
      type and "contrib/ltree"'s ltxtquery type.
    - Fix bug in "contrib/seg"'s GiST picksplit algorithm.
      This could result in considerable inefficiency, though not actually
      incorrect answers, in a GiST index on a seg column. If you have
      such an index, consider "REINDEX"ing it after installing this
      update. (This is identical to the bug that was fixed in
      "contrib/cube" in the previous update.)

postgresql-9.0 (9.0.2-1) unstable; urgency=low

  * New upstream bug fix release:
    - 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 "too many KnownAssignedXids" error during Hot Standby replay.
    - Fix race condition in lock acquisition during Hot Standby.
    - Avoid unnecessary conflicts during Hot Standby.
      This fixes some cases where replay was considered to conflict with
      standby queries (causing delay of replay or possibly cancellation
      of the queries), but there was no real conflict.
    - 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 corner-case bug when streaming replication is enabled
      immediately after creating the master database cluster.
    - 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.
    - Fix long-term memory leak in autovacuum launcher.
    - Avoid failure when trying to report an impending transaction
      wraparound condition from outside a transaction.
      This oversight prevented recovery after transaction wraparound got
      too close, because database startup processing would fail.
    - 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.
    - Add missing support in "DROP OWNED BY" for removing foreign data
      wrapper/server privileges belonging to a user.
    - 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.
    - Fix crash when inline-ing a set-returning function whose argument
      list contains a reference to an inline-able user function.
    - Behave correctly if ORDER BY, LIMIT, FOR UPDATE, or WITH is
      attached to the VALUES part of INSERT ... VALUES.
    - Make the OFF keyword unreserved.
      This prevents problems with using off as a variable name in
      PL/pgSQL. That worked before 9.0, but was now broken because
      PL/pgSQL now treats all core reserved words as reserved.
    - 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 "could not find pathkey item to sort" planner failure with
      comparison of whole-row Vars.
    - 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.
    - Retry after receiving an invalid response packet from a RADIUS
      authentication server.
      This fixes a low-risk potential denial of service condition.
    - 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 errors in psql's Unicode-escape support.
    - Speed up parallel pg_restore when the archive contains many large
      objects (blobs).
    - Fix PL/pgSQL's handling of "simple" expressions to not fail in
      recursion or error-recovery cases.
    - Fix PL/pgSQL's error reporting for no-such-column cases.
      As of 9.0, it would sometimes report "missing FROM-clause entry for
      table foo" when "record foo has no field bar" would be more
      appropriate.
    - Fix PL/Python to honor typmod (i.e., length or precision
      restrictions) when assigning to tuple fields.
      This fixes a regression from 8.4.
    - 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 buffer overrun in "contrib/pg_upgrade".
    - Fix memory leak in "contrib/xml2"'s XPath query functions.

postgresql-9.0 (9.0.1-2) unstable; urgency=low

  * debian/control: Build against libedit instead of libreadline. We can't
    simultaneously link against readline (GPL) and libssl (incompatible with
    GPL). (Closes: #603599)

postgresql-9.0 (9.0.1-1) unstable; urgency=low

  * New upstream security/bug fix release:
    - 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).
    - Improve pg_get_expr() security fix so that the function can still
      be used on the output of a sub-select.
    - 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 join removal's handling of placeholder expressions.
    - Fix possible duplicate scans of UNION ALL member relations.
    - Prevent infinite loop in ProcessIncomingNotify() after unlistening.
    - Prevent show_session_authorization() from crashing within
      autovacuum processes.
    - 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.
    - Make psql recognize "DISCARD ALL" as a command that should not be
      encased in a transaction block in autocommit-off mode.
    - Update build infrastructure and documentation to reflect the source
      code repository's move from CVS to Git.

postgresql-9.0 (9.0.0-3) unstable; urgency=low

  * debian/postgresql-9.0.preinst: Add missing debhelper token.

    belong together.
  * Merge 06-libpq-defaultsocketdir.patch and 11-pg_regress-socketpath.patch
    into 51-default-sockets-in-var.patch, they really belong together.
  * Re-enumerate 10-tutorial-README.patch and
    13-pg_service.conf_directory_doc.patch to 5x-*, since they are Debian
    specific.
