+== Applied Patches ==
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- Bump minor library version numbers, for 9.1 release.
+</p>
+
+<p>
+- In pgsql/src/tools/RELEASE_CHANGES, document bump of minor library
+  version numbers.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, spellcheck 9.0 release
+  notes.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, 9.0 release note
+  improvements Erik Rijkers
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, restore pl/pgsql default
+  install release note item.
+</p>
+
+<p>
+- In pg_upgrade, prevent psql AUTOCOMMIT=off by not loading .psqlrc.
+</p>
+
+<p>
+- In pgsql/src/tools/fsync/test_fsync.c, print each test_fsync
+  description while test is running, rather than at the end.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/exec.c, in pg_upgrade, report /bin
+  directory checks independent of /data checks.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/option.c, remove incorrect email address
+  for pg_upgrade bug reports.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/server.c, on Win32, pg_upgrade cannot
+  sent any server log output to the log file because of file access
+  limitations on that platform.
+</p>
+
+<p>
+- Backpatch pg_upgrade fixes to 9.0: 1. In pg_upgrade, prevent psql
+  AUTOCOMMIT=off by not loading .psqlrc.  2. In pg_upgrade, report
+  /bin directory checks independent of /data checks.  3. Remove
+  incorrect email address for pg_upgrade bug reports.  4. On Win32,
+  pg_upgrade cannot sent any server log output to the log file because
+  of file access limitations on that platform.
+</p>
+
+<p>
+- In pgsql/src/backend/commands/tablespace.c, simplify missing
+  tablespace replay error hint message, but only in HEAD so we don't
+  need to re-translate for 9.0.
+</p>
+
+<p>
+- In pgsql/src/interfaces/libpq/fe-connect.c, add SO_PEERCRED check in
+  new unix domain socket permission checking code.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Make NestLoop plan nodes pass outer-relation variables into their
+  inner relation using the general PARAM_EXEC executor parameter
+  mechanism, rather than the ad-hoc kluge of passing the outer tuple
+  down through ExecReScan.  The previous method was hard to understand
+  and could never be extended to handle parameters coming from
+  multiple join levels.  This patch doesn't change the set of possible
+  plans nor have any significant performance effect, but it's
+  necessary infrastructure for future generalization of the concept of
+  an inner indexscan plan.  ExecReScan's second parameter is now
+  unused, so it's removed.
+</p>
+
+<p>
+- Teach EXPLAIN to print PARAM_EXEC Params as the referenced
+  expressions, rather than just $N.  This brings the display of
+  nestloop-inner-indexscan plans back to where it's been, and
+  incidentally improves the display of SubPlan parameters as well.  In
+  passing, simplify the EXPLAIN code by having it deal primarily in
+  the PlanState tree rather than separately searching Plan and
+  PlanState trees.  This is noticeably cleaner for subplans, and about
+  a wash elsewhere.  One small difference from previous behavior is
+  that EXPLAIN will no longer qualify local variable references in
+  inner-indexscan plan nodes, since it no longer sees such nodes as
+  possibly referencing multiple tables.  Vars referenced through
+  PARAM_EXEC Params are still forcibly qualified, though, so I don't
+  think the display is any more confusing than before.  Adjust a
+  couple of examples in the documentation to match this behavior.
+</p>
+
+<p>
+- Allow full SSL certificate verification (wherein libpq checks its
+  host name parameter against server cert's CN field) to succeed in
+  the case where both host and hostaddr are specified.  As with the
+  existing precedents for Kerberos, GSSAPI, SSPI, it is the calling
+  application's responsibility that host and hostaddr match up --- we
+  just use the host name as given.  Per bug #5559 from Christopher
+  Head.  In passing, make the error handling and messages for the
+  no-host-name-given failure more consistent among these four cases,
+  and correct a lie in the documentation: we don't attempt to
+  reverse-lookup host from hostaddr if host is missing.  Back-patch to
+  8.4 where SSL cert verification was introduced.
+</p>
+
+<p>
+- In pgsql/src/bin/pg_dump/pg_dump.c, fix several problems in
+  pg_dump's handling of SQL/MED objects, notably failure to dump a
+  PUBLIC user mapping correctly, as per bug #5560 from Shigeru Hanada.
+  Use the pg_user_mappings view rather than trying to access
+  pg_user_mapping directly, so that the code doesn't fail when run by
+  a non-superuser.  And clean up some minor carelessness such as
+  unsafe usage of fmtId().  Back-patch to 8.4 where this code was
+  added.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/high-availability.sgml, use an <xref> for
+  restore_command reference.  Marko Tiikkaja.
+</p>
+
+<p>
+- In pgsql/src/backend/commands/opclasscmds.c, remove duplicate code
+  in DefineOpFamily().  The code was probably meant to be this way all
+  along, since the subroutine CreateOpFamily previously had only one
+  caller.  But it wasn't.  KaiGai Kohei.
+</p>
+
+<p>
+- In pgsql/src/backend/executor/execUtils.c, remove a sanity check in
+  the exclusion-constraint code that prevented users from defining
+  non-self-conflicting constraints.  Jeff Davis.  Note: I (tgl)
+  objected to removing this check in 9.0 on the grounds that it was an
+  important sanity check in new, poorly tested code.  However, it
+  should be all right to remove it for 9.1, since we'll get field
+  testing from the 9.0 branch.
+</p>
+
+<p>
+- Add support for dividing money by money (yielding a float8 result)
+  and for casting between money and numeric.  Andy Balholm, reviewed
+  by Kevin Grittner
+</p>
+
+<p>
+- Add a log_file_mode GUC that allows control of the file permissions
+  set on log files created by the syslogger process.  In passing, make
+  unix_file_permissions display its value in octal, same as
+  log_file_mode now does.  Martin Pihlak
+</p>
+
+<p>
+- In pgsql/src/interfaces/libpq/fe-connect.c, fix thinko in recent
+  patch: 'sock' should be 'conn->sock'.
+</p>
+
+<p>
+- In pgsql/src/interfaces/libpq/fe-connect.c, fix up poor handling of
+  unsupported-platform case in requirepeer patch.
+</p>
+
+<p>
+- Allow ORDER BY/GROUP BY/etc items to match targetlist items
+  regardless of any implicit casting previously applied to the
+  targetlist item.  This is reasonable because the implicit cast, by
+  definition, wasn't written by the user; so we are preserving the
+  expected behavior that ORDER BY items match textually equivalent
+  tlist items.  The case never arose before because there couldn't be
+  any implicit casting of a top-level SELECT item before we process
+  ORDER BY etc.  But now it can arise in the context of aggregates
+  containing ORDER BY clauses, since the "targetlist" is the
+  already-casted list of arguments for the aggregate.  The net effect
+  is that the datatype used for ORDER BY/DISTINCT purposes is the
+  aggregate's declared input type, not that of the original input
+  column; which is a bit debatable but not horrendous, and to do
+  otherwise would require major rework that doesn't seem justified.
+  Per bug #5564 from Daniel Grace.  Back-patch to 9.0 where aggregate
+  ORDER BY was implemented.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/error/elog.c, remove unnecessary "Not
+  safe to send CSV data" complaint from elog.c's fallback path when
+  CSV logging is configured but not yet operational.  It's sufficient
+  to send the message to stderr, as we were already doing, and the
+  "Not safe" gripe has already confused at least two core members ...
+  Backpatch to 9.0, but not further --- doesn't seem appropriate to
+  change this behavior in stable branches.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- In pgsql/src/backend/utils/mmgr/portalmem.c, oops, in the previous
+  fix to prevent a cursor that's being used in a FOR loop from being
+  dropped, I missed subtransaction cleanup.  Pinned portals must be
+  dropped at subtransaction cleanup just as they are at main
+  transaction cleanup.  Per bug #5556 by Robert Walker.  Backpatch to
+  8.0, 7.4 didn't have subtransactions.
+</p>
+
+<p>
+- Add a paragraph explaining what restartpoints are.  Mention that
+  wal_keep_segments does not take effect during recovery.  Fujii Masao
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/wal.sgml, fix typo spotted by Thom Brown.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- Add server authentication over Unix-domain sockets.  This adds a
+  libpq connection parameter requirepeer that specifies the user name
+  that the server process is expected to run under.  Reviewed by
+  KaiGai Kohei.
