+<h2>Applied Patches</h2>
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- In pgsql/src/backend/optimizer/plan/planagg.c, when adding a "target
+  IS NOT NULL" indexqual to the plan for an index-optimized MIN or
+  MAX, we must take care to insert the added qual in a legal place
+  among the existing indexquals, if any.  The btree index AM requires
+  the quals to appear in index-column order.  We didn't have to worry
+  about this before because "target IS NOT NULL" was just treated as a
+  plain scan filter condition; but as of 9.0 it can be an index qual
+  and then it has to follow the rule.  Per report from Ian Barwick.
+</p>
+
+<p>
+- In pgsql/src/backend/optimizer/prep/prepunion.c, fix incorrect patch
+  that removed permission checks on inheritance child tables --- the
+  parent table no longer got checked, either.  Per bug #5458 from
+  Takahiro Itagaki.
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster/pgarch.c, cause the archiver process
+  to adopt new postgresql.conf settings (particularly archive_command)
+  as soon as possible, namely just before issuing a new call of
+  archive_command, even when there is a backlog of files to be
+  archived.  The original coding would only absorb new settings after
+  clearing the backlog and returning to the outer loop.  Per
+  discussion.  Back-patch to 8.3.  The logic in prior versions is a
+  bit different and it doesn't seem worth taking any risks of breaking
+  it.
+</p>
+
+<p>
+- Add PKST to the default set of timezone abbreviations.  Per
+  discussion, if we have PKT in there then PKST should be too.  Also,
+  fix mistaken claim that these abbrevs are not known to zic.
+</p>
+
+<p>
+- Update time zone data files to tzdata release 2010j: DST law changes
+  in Argentina, Australian Antarctic, Bangladesh, Mexico, Morocco,
+  Pakistan, Palestine, Russia, Syria, Tunisia.  Historical corrections
+  for Taiwan.
+</p>
+
+<p>
+- Clean up unnecessary unportability and compiler warnings by removing
+  the cmp parameter for pg_scandir().  The code failed to support this
+  anyway for Sun/Windows, so pretending we could accept a parameter
+  other than NULL was just asking for trouble.
+</p>
+
+<p>
+- Hook pg_upgrade into the contrib makefile structure so it gets built
+  on the buildfarm.
+</p>
+
+<p>
+- Preliminary release notes for releases 8.4.4, 8.3.11, 8.2.17,
+  8.1.21, 8.0.25, 7.4.29.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade_support/Makefile, fix wrong subdir.  Per
+  buildfarm.
+</p>
+
+<p>
+- Use "TOAST table" in place of the vague, not-used-elsewhere phrase
+  "supplementary storage table".
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/rules.sgml, use an entity instead of non-ASCII
+  letter.  Thom Brown.
+</p>
+
+<p>
+- Fix up lame idea of not using autoconf to determine if platform has
+  scandir().  Should fix buildfarm failures.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/file.c, spell __darwin__ correctly, to
+  suppress compiler warning on OSX.
+</p>
+
+<p>
+- In pg_upgrade, get rid of unsafe sprintf and snprintf usages.  Per
+  compiler warnings.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/controldata.c, remove another unsafe use
+  of random data as a format string.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/info.c, fix another obvious bug pointed
+  out by a compiler warning.
+</p>
+
+<p>
+- In pgsql/src/include/port.h, spell __NetBSD__ the same way
+  everywhere.  Per Giles Lean.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/pg_restore.sgml, improve documentation of
+  pg_restore's -l and -L switches to point out their interactions with
+  filtering switches, such as -n and -t.  Per a complaint from Russell
+  Smith.
+</p>
+
+<p>
+- Ensure that pg_restore -l will output DATABASE entries whether or
+  not -C is specified.  Per bug report from Russell Smith and ensuing
+  discussion.  Since this is a corner case behavioral change, I'm
+  going to be conservative and not back-patch it.  In passing, also
+  rename the RestoreOptions field for the -C switch to something less
+  generic than "create".
+</p>
+
+<p>
+ITAGAKI Takahiro committed:
+</p>
+
+<p>
+- In pgsql/src/backend/catalog/pg_proc.c, set per-function GUC
+  settings during validating the function.  Now validators work
+  properly even when the settings contain parameters that affect
+  behavior of the function, like search_path.  Reported by Erwin
+  Brandstetter.
+</p>
+
+<p>
+- In pgsql/src/backend/po/ja.po, remove CRs.
+</p>
+
+<p>
+Robert Haas committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/cluster.sgml, mention related ALTER TABLE
+  variants in documentation for CLUSTER.  As suggested by Andy Lester.
+</p>
+
+<p>
+- In pgsql/src/include/utils/rbtree.h, change typedef for
+  rb_appendator to avoid conflict with C++ reserved words.  Fixes a
+  complaint from src/tools/pginclude/cpluspluscheck reported by Peter
+  Eisentraut.
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster/postmaster.c, we now accept
+  read-only connections in state PM_RECOVERY_CONSISTENT.
+</p>
+
+<p>
+- Rename PM_RECOVERY_CONSISTENT and PMSIGNAL_RECOVERY_CONSISTENT.  The
+  new names PM_HOT_STANDBY and PMSIGNAL_BEGIN_HOT_STANDBY more
+  accurately reflect their actual function.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/xfunc.sgml, fix longstanding typo in V1
+  calling conventions documentation.  Erik Rijkers
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/xfunc.sgml, insert line breaks in two places
+  in SQL functions documentation.  This avoids a formatting problem in
+  the PDF output.  In the HTML output this isn't necessary, but we've
+  done similar things elsewhere in the documentation so I think it's
+  OK to do it here, too.  I've refrained from breaking a longish error
+  message which also causes problems for the PDF output, because that
+  would make the HTML output look wrong.  Erik Rijkers.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- Add pg_upgrade to /contrib;  will be in 9.0 beta2.  Add
+  documentation.  Supports migration from PG 8.3 and 8.4.
+</p>
+
+<p>
+- Add pgsql/contrib/pg_upgrade/TODO file to CVS.
+</p>
+
+<p>
+- Add pgsql/contrib/pg_upgrade/IMPLEMENTATION file to CVS.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/info.c, small formatting adjustment.
+</p>
+
+<p>
+- Add PGFILEDESC description to Makefiles for all /contrib
+  executables.  Add PGAPPICON to all executable makefiles.
+</p>
+
+<p>
+- Move pg_upgrade TODO to TODO wiki.
+</p>
+
+<p>
+- In pgsql/src/backend/Makefile, remove Makefile PGFILEDESC tag that
+  the postmaster is an executable.
+</p>
+
+<p>
+- In pgsql/src/backend/Makefile, update comment about why postmaster
+  doesn't get an icon.
+</p>
+
+<p>
+- Move pg_upgrade shared library out into its own /contrib directory
+  (pg_upgrade_support).
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, update release notes to
+  current.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, fix HISTORY.html build using
+  </link>, not </>.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/pgupgrade.sgml, comment out EnterpriseDB
+  Advanced Server mention in SGML docs.
+</p>
+
+<p>
+- Remove all mentions of EnterpriseDB Advanced Server from pg_upgrade;
+  EDB must maintain their own patch set for this.
+</p>
+
+<p>
+- Use NAMEDATALEN instead of local define.  Modify path separators for
+  Win32.  Per ideas from Takahiro Itagaki.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/file.c, change bsdi define to __bsdi__.
+</p>
+
+<p>
+- Use __bsdi__ consistently.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/file.c, adjust pg_upgrade BSD defines
+  for scandir(), per report from Giles Lean.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- Update config.guess and config.sub.
+</p>
+
+<p>
+- Translation update
+</p>
+
+<p>
+- Fix vpath installation from distribution tarball (bug #5447)
+</p>
+
+<p>
+- In pgsql/src/nls-global.mk, avoid error from mkdir if no languages
+  are to be installed mkinstalldirs used to handle no arguments, but
+  mkdir doesn't.  Also remove the .SILENT setting, that was previously
+  removed from Makefile.global as well.
+</p>
+
+<p>
+- Translation update
+</p>
+
+<p>
+Simon Riggs committed:
+</p>
+
+<p>
+- In pgsql/src/backend/tcop/postgres.c, give most recovery conflict
+  errors a retryable error code.  From recent requests and discussions
+  with Yeb Havinga and Kevin Grittner.
+</p>
+
+<p>
+- Cleanup initialization of Hot Standby. Clarify working with
+  reanalysis of requirements and documentation on
+  LogStandbySnapshot().  Fixes two minor bugs reported by Tom Lane
+  that would lead to an incorrect snapshot after transaction
+  wraparound.  Also fix two other problems discovered that would give
+  incorrect snapshots in certain cases.  ProcArrayApplyRecoveryInfo()
+  substantially rewritten.  Some minor refactoring of
+  xact_redo_apply() and ExpireTreeKnownAssignedTransactionIds().
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xact.c, ensure that top level
+  aborts call XLogSetAsyncCommit().  Not doing so simply leads to data
+  waiting in wal_buffers which then causes later commits to
+  potentially do emergency writes and for all forms of replication to
+  be potentially delayed without need or benefit.  Issue pointed out
+  exactly by Fujii Masao, following bug report by Robert Haas on a
+  separate though related topic.
+</p>
+
+<p>
+- Add many new Asserts in code and fix simple bug that slipped through
+  without them, related to previous commit.  Report by Bruce Momjian.
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlog.c, fix bug in processing of
+  checkpoint time for max_standby_delay.  Latest log time was
+  incorrectly set, typically leading to dates in the past, which would
+  cause more cancellations in Hot Standby on a quiet server.
+</p>
+
+<p>
+Andrew Dunstan committed:
+</p>
+
+<p>
+- In pgsql/src/tools/msvc/Mkvcbuild.pm, add missing library and
+  include support for pg_upgrade to MSVC build system.
+</p>
+
+<p>
+Magnus Hagander committed:
+</p>
+
+<p>
+- Fix some spelling errors.  Thom Brown.
+</p>
+
+<p>
+- In pgsql/src/tools/msvc/Mkvcbuild.pm, properly support multi-line
+  entires (such as OBJS=) when building PROGRAM, not just MODULE, in
+  contrib.
+</p>
+
+<p>
+- Assorted fixes to make pg_upgrade build on MSVC.  1. There is no
+  chmod() on Windows.  2. Must always use the 3-parameter version of
+  open().  3. There is no dynloader.h - but it also appears unnecessary
+  on all platforms.  4. Don't include shlobj.h because it causes compile
+  errors, and from what I can see it's not actually used.  This may
+  need to be added back for mingw and/or cygwin in the worst case.
+</p>
+
+<p>
+Marc Fournier committed:
+</p>
+
+<p>
+- Tag 8.4.4, 8.3.11, 8.2.17, 8.1.21, 8.0.25, 7.4.29.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- In pgsql/contrib/pg_standby/pg_standby.c, fix typos in comments,
+  spotted by Josh Kupershmidt.
+</p>
+
+<h2>Rejected Patches (for now)</h2>
+<p>
+Greg Sabino Mullane's patch to change pg_dump not to use CREATE OR
+REPLACE LANGUAGE when talking to pre-9.0 databases.  There never was a
+guarantee that the output of pg_dump would be backward-compatible.
+</p>
+
+<h2>Pending Patches</h2>
+<p>
+ITAGAKI Takahiro sent in a patch to change the search_path check for
+function bodies to the current search_path, where they had been using
+the one at create time.
+</p>
+
+<p>
+Mike Fowler sent in a patch to add a function xpath_exists() for 9.1.
+</p>
+
+<p>
+Alexander Korotkov sent in two revisions of a patch to make the
+levenshtein distance function in contrib/fuzzystrmatch work with
+multibyte character sets in 9.1.
+</p>
+
+<p>
+Simon Riggs sent in a patch to change the startup code for Hot
+Standby.
+</p>
+
+<p>
+Stephen Frost sent in a patch to add a handler for SIGCHLD to psql.
+This is for 9.1.
+</p>
+
+<p>
+Simon Riggs sent in a patch to add a keepalive message to ensure
+max_standby_delay is useful.  Heikki Linnakangas responded with one
+which rearranges the walsender loops slightly so that XLogSend() now
+only sends up to MAX_SEND_SIZE bytes (== XLOG_SEG_SIZE / 2) in one
+round and returns to the main loop after that even if there's unsent
+WAL, and the main loop no longer sleeps if there's unsent WAL.  Simon
+Riggs sent in another with wait processing cleanup.
+</p>
+
+<p>
+Joachim Wieland sent in a patch to fix some locking behavior for 9.1
+in the case of SERIALIZABLE transactions.
+</p>
+
+<p>
+Robert Haas sent in a patch to implement a fix for smart shutdown in
+recovery.
+
+</p>
+
