* New upstream security/bug fix release (LP: #1457093)
  - Avoid possible crash when client disconnects just before the
    authentication timeout expires.
    If the timeout interrupt fired partway through the session shutdown
    sequence, SSL-related state would be freed twice, typically causing a
    crash and hence denial of service to other sessions. Experimentation
    shows that an unauthenticated remote attacker could trigger the bug
    somewhat consistently, hence treat as security issue. (CVE-2015-3165)

  - Improve detection of system-call failures
    Our replacement implementation of snprintf() failed to check for errors
    reported by the underlying system library calls; the main case that
    might be missed is out-of-memory situations. In the worst case this
    might lead to information exposure, due to our code assuming that a
    buffer had been overwritten when it hadn't been. Also, there were a few
    places in which security-relevant calls of other system library
    functions did not check for failure.
    It remains possible that some calls of the *printf() family of functions
    are vulnerable to information disclosure if an out-of-memory error
    occurs at just the wrong time. We judge the risk to not be large, but
    will continue analysis in this area. (CVE-2015-3166)

  - In contrib/pgcrypto, uniformly report decryption failures as Wrong key
    or corrupt data
    Previously, some cases of decryption with an incorrect key could report
    other error message texts. It has been shown that such variance in
    error reports can aid attackers in recovering keys from other systems.
    While it's unknown whether pgcrypto's specific behaviors are likewise
    exploitable, it seems better to avoid the risk by using a
    one-size-fits-all message. (CVE-2015-3167)

  - Protect against wraparound of multixact member IDs
    Under certain usage patterns, the existing defenses against this might
    be insufficient, allowing pg_multixact/members files to be removed too
    early, resulting in data loss.
    The fix for this includes modifying the server to fail transactions that
    would result in overwriting old multixact member ID data, and improving
    autovacuum to ensure it will act proactively to prevent multixact member
    ID wraparound, as it does for transaction ID wraparound.

* postgresql-9.4.preinst: Output detailed dump-reload instructions when
  refusing the package upgrade, and also add a NEWS item about it.
  (Closes: #764705)
* Add libipc-run-perl for the regression tests which otherwise skip large
  parts.
* Update Standards-Version.

6. By Christoph Berg on 2014-10-07

* New upstream beta version.
  + Catalog version number changed, older 9.4 clusters need to be dumped and
    reloaded.
  + Regexp regression fixed. (Closes: #760564)
  + CACHE_LINE_SIZE definition renamed to mitigate conflict on *BSD.
    (Closes: #763098)

[ Martin Pitt ]
* Add missing logrotate test dependency.

[ Christoph Berg ]
* Set Multi-Arch: foreign in postgresql-client-9.4 and postgresql-doc-9.4.
  (Closes: #757520; do it even on non-multiarch dists, it doesn't hurt.)
* Fix postgresql_fdw in description, spotted by Andrei Popescu, thanks!
  (Closes: #762389)

5. By Colin Watson on 2014-08-21

Rebuild for Perl 5.20.0.

* New upstream beta version.
  + Secure Unix-domain sockets of temporary postmasters started during make
    check (Noah Misch)

    Any local user able to access the socket file could connect as the
    server's bootstrap superuser, then proceed to execute arbitrary code as
    the operating-system user running the test, as we previously noted in
    CVE-2014-0067. This change defends against that risk by placing the
    server's socket in a temporary, mode 0700 subdirectory of /tmp.

* postgresql-9.4.preinst: Fail upgrade when upgrading from beta1, the
  catalog version changed. People should dump/remove their old clusters
  first.
* Use util-linux' uuid lib as backend for the uuid-ossp extension
  (--with-uuid=e2fs).
* Enable sepgsql (--with-selinux). On systems with libselinux1-dev < 2.1.10,
  this is automatically disabled.
* Revert multiarch for libpq-dev and libecpg-dev. (Closes: #750111, #750112)
* Remove our pg_regress patches to support --host=/path. Implemented
  upstream as fix for CVE-2014-0067.
* debian/copyright: Say that there are various copyright holders for the
  contrib modules. (Hello Lintian!)
* Update Vcs URLs.

3. By Christoph Berg on 2014-05-30

* Update watch file for 9.4.
* Enable multiarch support in libpq and friends. (Closes: #706849)
  Support is automatically disabled when the distribution does not support
  it.
* Stop providing postgresql-dbg in postgresql-9.4-dbg. Its only purpose was
  to conflict with other postgresql-*-dbg packages, and that's no longer
  needed with build-id debug symbols.
* Skip -pie on 32bit archs for performance and stability reasons.
  Closes: #749686; details at
  http://<email address hidden>
* Update contrib copyright statements, and move them to a separate file.
  Thanks to Thorsten Alteholz for reviewing the package.

* Update for 9.4. Packaging based on 9.3 branch.
* Bump to debhelper 9 to get debug symbol files based on build-ids.
