+<h2>Applied Patches</h2>
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Back-patch today's memory management fixups in contrib/xml2.  Prior
+  to 8.3, these changes are not critical for compatibility with core
+  Postgres, since core had no libxml2 calls then.  However there is
+  still a risk if contrib/xml2 is used along with libxml2
+  functionality in Perl or other loadable modules.  So back-patch to
+  all versions.  Also back-patch addition of regression tests.  I'm
+  not sure how many of the cases are interesting without the
+  interaction with core xml code, but a silly regression test is still
+  better than none at all.
+</p>
+
+<p>
+- Remove xmlCleanupParser calls from contrib/xml2.  These are
+  unnecessary and probably dangerous.  I don't see any immediate risk
+  situations in the core XML support or contrib/xml2 itself, but there
+  could be issues with external uses of libxml2, and in any case it's
+  an accident waiting to happen.
+</p>
+
+<p>
+- In pgsql/src/port/copydir.c, buildfarm still unhappy, so I'll bet
+  it's EACCES not EPERM.
+</p>
+
+<p>
+- Fix contrib/xml2 so regression test still works when it's built
+  without libxslt.  This involves modifying the module to have a
+  stable ABI, that is, the xslt_process() function still exists even
+  without libxslt.  It throws a runtime error if called, but doesn't
+  prevent executing the CREATE FUNCTION call.  This is a good thing
+  anyway to simplify cross-version upgrades.
+</p>
+
+<p>
+- In pgsql/src/pl/plpgsql/src/gram.y, cause plpgsql to throw an error
+  if "INTO rowtype_var" is followed by a comma.  Per bug #5352, this
+  helps to provide a useful error message if the user tries to do
+  something presently unsupported, namely use a rowtype variable as a
+  member of a multiple-item INTO list.
+</p>
+
+<p>
+- In pgsql/src/pl/plpgsql/src/gram.y, instead of trying (and failing)
+  to allow <<label>> at the end of a DECLARE section, throw an error
+  message saying explicitly that the label must go before DECLARE.
+  Per investigation of a recent pgsql-novice question, this code did
+  not work as intended in any modern PG version, maybe not ever.
+  Allowing such a thing would only create ambiguity anyway, so it
+  seems better to remove it than fix it.
+</p>
+
+<p>
+- Export xml.c's libxml-error-handling support so that contrib/xml2
+  can use it too, instead of duplicating the functionality (badly).  I
+  renamed xml_init to pg_xml_init, because the former seemed just a
+  bit too generic to be safe as a global symbol.  I considered
+  likewise renaming xml_ereport to pg_xml_ereport, but felt that the
+  reference to ereport probably made it sufficiently PG-centric
+  already.
+</p>
+
+<p>
+- Make contrib/xml2 use core xml.c's error handler, when available
+  (that is, in versions >= 8.3).  The core code is more robust and
+  efficient than what was there before, and this also reduces risks
+  involved in swapping different libxml error handler settings.
+  Before 8.3, there is still some risk of problems if add-on modules
+  such as Perl invoke libxml without setting their own error handler.
+  Given the lack of reports I'm not sure there's a risk in practice,
+  so I didn't take the step of actually duplicating the core code into
+  older contrib/xml2 branches.  Instead I just tweaked the existing
+  code to ensure it didn't leave a dangling pointer to short-lived
+  memory when throwing an error.
+</p>
+
+<p>
+- Fix a couple of places that would loop forever if attempts to read a
+  stdio file set ferror() but never set feof().  This is known to be
+  the case for recent glibc when trying to read a directory as a file,
+  and might be true for other platforms/cases too.  Per report from Ed
+  L.  (There is more that we ought to do about his report, but this is
+  one easily identifiable issue.)
+</p>
+
+<p>
+- In pgsql/src/backend/libpq/hba.c, when reading pg_hba.conf and
+  similar files, do not treat @file as an inclusion unless (1) the @
+  isn't quoted and (2) the filename isn't empty.  This guards against
+  unexpectedly treating usernames or other strings in "flat files" as
+  inclusion requests, as seen in a recent trouble report from Ed L.
+  The empty-filename case would be guaranteed to misbehave anyway,
+  because our subsequent path-munging behavior results in trying to
+  read the directory containing the current input file.  I think this
+  might finally explain the report at
+  <a href="http://archives.postgresql.org/pgsql-bugs/2004-05/msg00132.php">http://archives.postgresql.org/pgsql-bugs/2004-05/msg00132.php</a> of a
+  crash after printing "authentication file token too long, skipping",
+  since I was able to duplicate that message (though not a crash) on a
+  platform where stdio doesn't refuse to read directories.  We never
+  got far in investigating that problem, but now I'm suspicious that
+  the trigger condition was an @ in the flat password file.
+  Back-patch to all active branches since the problem can be
+  demonstrated in all branches except HEAD.  The test case, creating a
+  user named "@", doesn't cause a problem in HEAD since we got rid of
+  the flat password file.  Nonetheless it seems like a good idea to
+  not consider quoted @ as a file inclusion spec, so I changed HEAD
+  too.
+</p>
+
+<p>
+- In pgsql/src/backend/catalog/aclchk.c, fix warning messages in
+  restrict_and_check_grant() to include the column name when warning
+  about column-level privileges.  This is more useful than before and
+  makes the apparent duplication complained of by Piyush Newe not so
+  duplicate.  Also fix lack of quote marks in a related message text.
+  Back-patch to 8.4, where column-level privileges were introduced.
+  Stephen Frost
+</p>
+
+<p>
+- Update time zone data files to tzdata release 2010c: DST law changes
+  in Bangladesh, Mexico, Paraguay.
+</p>
+
+<p>
+Magnus Hagander committed:
+</p>
+
+<p>
+- In pgsql/src/backend/libpq/hba.c, it's clearly now pointless to do
+  backwards compatible parsing of this, since we released a version
+  without it, so remove the comment that says we might want to do
+  that.
+</p>
+
+<p>
+- Add --psqlrc=FILENAME parameter to psql, to process an explicitly
+  named file instead of ~/.psqlrc on startup.
+</p>
+
+<p>
+- Revert patch for --psqlrc=FILENAME in psql.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- Fix numericlocale psql option when used with a null string and latex
+  and troff formats; a null string must not be formatted as a numeric.
+  The more exotic formats latex and troff also incorrectly formatted
+  all strings as numerics when numericlocale was on.  Backpatch to 8.1
+  where numericlocale option was added.  This fixes bug #5355 reported
+  by Andy Lester.
+</p>
+
+<p>
+- In pgsql/src/bin/psql/print.c, fix translation of strings in psql \d
+  output (translation in headers worked, but not in cells).
+</p>
+
+<p>
+- Fix pg_dump of ACLs of foreign servers. The command to grant/revoke
+  privileges of foreign servers is "GRANT ... ON *FOREIGN* SERVER
+  ...".
+</p>
+
+<p>
+- In pgsql/src/backend/parser/parse_coerce.c, fix IsBinaryCoercible to
+  not confuse a cast using in/out functions with binary compatibility.
+  Backpatch to 8.4 where INOUT casts were introduced.
+</p>
+
+<p>
+Andrew Dunstan committed:
+</p>
+
+<p>
+- In pgsql/src/tools/msvc/Solution.pm, add XSLT defines for MSVC
+  builds.
+</p>
+
+<p>
+- In pgsql/src/tools/msvc/Solution.pm, backpatch MSVC build fix for
+  XSLT.
+</p>
+
+<p>
+- In pgsql/src/tools/msvc/vcregress.pl, do not run regression tests
+  for contrib/xml2 on MSVC unless building with XML.
+</p>
+
+<p>
+- In pgsql/src/tools/msvc/Solution.pm, add missing library and include
+  dir for XSLT in MSVC builds.
+</p>
+
+<p>
+- In pgsql/src/tools/msvc/Solution.pm, make iconv work like other
+  optional libraries for MSVC.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/keywords.sgml, update keywords list for 9.0.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- Document the effect of max_standby_delay on increasing the delay of
+  data from master to slave, and discourage its use during
+  slave/master keep-xid-alive connections.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/config.sgml, adjust max_standby_delay
+  documentation to be clearer, and mention that two adjacent
+  long-running queries have much less than max_standby_delay before
+  query cancel is possible.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/adt/xml.c, pgindent run on xml.c in 8.3
+  branch, per request from Tom Lane.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/create_function.sgml, restructure CREATE
+  FUNCTION "NOTES" section to be shorter;  move items into proper
+  sections, per suggestion from Tom Lane.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/create_function.sgml, fix SGML markup.
+</p>
+
+<p>
+- Document that "Q" is ignored by to_date and to_timestamp.  Add C
+  comment about the behavior.  Document that quotes in to_date,
+  to_timestamp, to_number skip input characters.
+</p>
+
+<p>
+- In pgsql/src/bin/pg_dump/pg_dump.c, add C comment about DDL changes
+  possibly causing pg_dump errors.
+</p>
+
+<p>
+Michael Meskes committed:
+</p>
+
+<p>
+- In case the connection magically disappears libecpg only returns an
+  internal error sqlstate.  This change makes it return a correct
+  value.
