  [ Martin Pitt ]
  * New upstream security/bug fix release:
    - Protect against indirect security threats caused by index functions
      changing session-local state. This change prevents allegedly-immutable
      index functions from possibly subverting a superuser's session
      (CVE-2009-4136).
    - Reject SSL certificates containing an embedded null byte in the
      common name (CN) field. This prevents unintended matching of a
      certificate to a server or client name during SSL validation
      (CVE-2009-4034).
    - Fix hash index corruption. The 8.4 change that made hash indexes keep
      entries sorted by hash value failed to update the bucket splitting and
      compaction routines to preserve the ordering. So application of either
      of those operations could lead to permanent corruption of an index, in
      the sense that searches might fail to find entries that are present. To
      deal with this, it is recommended to REINDEX any hash indexes you may
      have after installing this update.
    - Fix possible crash during backend-startup-time cache initialization.
    - Avoid crash on empty thesaurus dictionary.
    - Prevent signals from interrupting VACUUM at unsafe times.
    - Fix possible crash due to integer overflow in hash table size
      calculation.
    - Fix crash if a DROP is attempted on an internally-dependent object.
    - Fix very rare crash in inet/cidr comparisons.
    - Ensure that shared tuple-level locks held by prepared transactions
      are not ignored.
    - Fix premature drop of temporary files used for a cursor that is
      accessed within a subtransaction.
    - Fix memory leak in syslogger process when rotating to a new CSV
      logfile.
    - Fix memory leak in postmaster when re-parsing "pg_hba.conf".
    - Make FOR UPDATE/SHARE in the primary query not propagate into WITH
      queries.
    - Fix bug with a WITH RECURSIVE query immediately inside another one.
    - Fix concurrency bug in hash indexes.
    - Fix incorrect logic for GiST index page splits, when the split
      depends on a non-first column of the index.
    - Fix wrong search results for a multi-column GIN index with
      fastupdate enabled.
    - Fix bugs in WAL entry creation for GIN indexes.
    - Don't error out if recycling or removing an old WAL file fails at
      the end of checkpoint.
    - Fix PAM password processing to be more robust.
      The previous code is known to fail with the combination of the
      Linux pam_krb5 PAM module with Microsoft Active Directory as the
      domain controller. It might have problems elsewhere too, since it
      was making unjustified assumptions about what arguments the PAM
      stack would pass to it.
    - Raise the maximum authentication token (Kerberos ticket) size in
      GSSAPI and SSPI authentication methods. While the old 2000-byte limit
      was more than enough for Unix Kerberos implementations, tickets issued
      by Windows Domain Controllers can be much larger.
    - Ensure that domain constraints are enforced in constructs like
      ARRAY[...]::domain, where the domain is over an array type.
    - Fix foreign-key logic for some cases involving composite-type
      columns as foreign keys.
    - Ensure that a cursor's snapshot is not modified after it is created.
    - Fix CREATE TABLE to properly merge default expressions coming from
      different inheritance parent tables. This used to work but was broken in
      8.4.
    - Re-enable collection of access statistics for sequences. This used to
      work but was broken in 8.3.
    - Fix processing of ownership dependencies during CREATE OR REPLACE
      FUNCTION.
    - Fix incorrect handling of WHERE "x"="x" conditions.
      In some cases these could get ignored as redundant, but they aren't
      -- they're equivalent to "x" IS NOT NULL.
    - Fix incorrect plan construction when using hash aggregation to
      implement DISTINCT for textually identical volatile expressions
    - Fix Assert failure for a volatile SELECT DISTINCT ON expression
    - Fix ts_stat() to not fail on an empty tsvector value
    - Make text search parser accept underscores in XML attributes
    - Fix encoding handling in xml binary input.
      If the XML header doesn't specify an encoding, we now assume UTF-8
      by default; the previous handling was inconsistent.
    - Fix bug with calling plperl from plperlu or vice versa.
    - Fix session-lifespan memory leak when a PL/Perl function is
      redefined.
    - Ensure that Perl arrays are properly converted to PostgreSQL arrays
      when returned by a set-returning PL/Perl function.
    - Fix rare crash in exception processing in PL/Python.
    - Fix ecpg problem with comments in DECLARE CURSOR statements
    - Fix ecpg to not treat recently-added keywords as reserved words
      This affected the keywords CALLED, CATALOG, DEFINER, ENUM,
      FOLLOWING, INVOKER, OPTIONS, PARTITION, PRECEDING, RANGE, SECURITY,
      SERVER, UNBOUNDED, and WRAPPER.
    - Re-allow regular expression special characters in psql's \df
      function name parameter.
    - Put FREEZE and VERBOSE options in the right order in the VACUUM
      command that "contrib/vacuumdb" produces.
    - Fix possible leak of connections when "contrib/dblink" encounters
      an error
    - Make the postmaster ignore any application_name parameter in
      connection request packets, to improve compatibility with future
      libpq versions.
