+</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.
