+<h2>Applied Patches</h2>
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- In pgsql/src/backend/utils/adt/arrayfuncs.c, revert dubious message
+ wording change.
+</p>
+
+<p>
+- Make to_timestamp and friends skip leading spaces before an integer
+ field, even when not in Fujii Masao mode. This improves
+ compatibility with Oracle and with our pre-8.4 behavior, as per bug
+ #4862. Add a couple of regression test cases for this. In passing,
+ get rid of the labeling of the individual test cases; doesn't seem
+ to be good for anything except causing extra work when inserting a
+ test... Brendan Jurd and Tom Lane
+</p>
+
+<p>
+- For bulk write operations (eg COPY IN), use a ring buffer of 16MB
+ instead of the 256KB limit originally enforced by a patch committed
+ 2008-11-06. Per recent test results, the smaller size resulted in
+ an undesirable decrease in bulk data loading speed, due to COPY
+ processing frequently getting blocked for WAL flushing. This area
+ might need more tweaking later, but this setting seems to be good
+ enough for 8.4.
+</p>
+
+<p>
+- Fix the makefiles to fail cleanly if Perl is needed but not present.
+ This used to work as intended, but got broken some time ago (a
+ quoted empty string is not an empty string), and got broken some
+ more by the changes to generate ecpg's preproc.y automatically.
+ Given all the unprotected uses of $(PERL) elsewhere, it seems best
+ to make use of the $(missing) script rather than trying to ensure
+ each such use is protected individually. Also fix various bits of
+ documentation that omitted to mention Perl as a requirement for
+ building from a CVS pull. Per a complaint from Robert Haas.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/adt/geo_ops.c, fix an ancient error in
+ dist_ps (distance from point to line segment), which a number of
+ other geometric operators also depend on. It miscalculated the
+ slope of the perpendicular to the given line segment anytime that
+ slope was other than 0, infinite, or +/-1. In some cases the error
+ would be masked because the true closest point on the line segment
+ was one of its endpoints rather than the intersection point, but in
+ other cases it could give an arbitrarily bad answer. Per bug #4872
+ from Nick Roosevelt. Bug goes clear back to Berkeley days, so patch
+ all supported branches. Make a couple of cosmetic adjustments while
+ at it.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/dml.sgml, provide a link to the UPDATE
+ reference page in the 'Updating Data' section of the docs. Per
+ suggestion from Brad Bowman.
+</p>
+
+<p>
+- In pgsql/contrib/pg_standby/pg_standby.c, make prior patch
+ pgindent-safe.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/error/elog.c, add
+ __attribute__((format_arg(1))) to the declaration of err_gettext(),
+ to restore gcc's ability to crosscheck format arguments within
+ elog.c. Noted in a test compilation with -Wformat-nonliteral
+ enabled.
+</p>
+
+<p>
+- Cleanup and code review for the patch that made bgwriter active
+ during archive recovery. Invent a separate state variable and
+ inquiry function for XLogInsertAllowed() to clarify some tests and
+ make the management of writing the end-of-recovery checkpoint less
+ klugy. Fix several places that were incorrectly testing InRecovery
+ when they should be looking at RecoveryInProgress or
+ XLogInsertAllowed (because they will now be executed in the bgwriter
+ not startup process). Clarify handling of bad LSNs passed to
+ XLogFlush during recovery. Use a spinlock for setting/testing
+ SharedRecoveryInProgress. Improve quite a lot of comments. Heikki
+ Linnakangas and Tom Lane.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/backup.sgml, marginal improvement of
+ description of recovery_end_command.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/monitoring.sgml, add a note about SystemTap vs
+ DTrace spelling of probe names.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-8.4.sgml, update release notes in
+ final preparation for 8.4.0.
+</p>
+
+<p>
+- In pgsql/doc/Makefile, revert addition of "o" to tar options. This
+ was intended to fix bug #4883, but the cure appears to be worse than
+ the disease. It turns out that GNU tar versions 1.14.x misinterpret
+ -o as --same-owner, not --no-same-owner, leading to exactly the
+ wrong behavior for both root and nonroot users. While that bug has
+ been fixed for nearly five years, these tar versions are still found
+ in the wild, notably in OS X 10.4. Given that #4883 was the first
+ complaint we'd heard, it's definitely not worth fixing at the risk
+ of breaking things for other users. Perhaps revisit at a later date
+ when we're not up against a release deadline.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/move.sgml, add more explicit note that the
+ parameters of MOVE are identical to FETCH. Per David Wheeler.
+</p>
+
+<p>
+- In pgsql/src/backend/access/gist/gistsplit.c, correct grammar in
+ picksplit debug messages
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/Makefile, man pages back to lowercase names,
+ with additional fixup to make the .so links work.
+</p>
+
+<p>
+- In pgsql/doc/Makefile, use $(TAR) instead of tar in makefiles.
+</p>
+
+<p>
+- In pgsql/doc/Makefile, extract tarballs with "o" option (tar xof),
+ to behave reasonably when run as root, as would usually be the case
+ during make install. Per bug #4883.
+</p>
+
+<p>
+- Translation updates for 8.4 release. File that are translated less
+ than 80% have been removed, as per new translation team policy.
+</p>
+
+<p>
+Marc Fournier committed:
+</p>
+
+<p>
+- Bundle RC2.
+</p>
+
+<p>
+- Bundle v8.4.0.
+</p>
+
+<p>
+Magnus Hagander committed:
+</p>
+
+<p>
+- Properly initialize SSL engines when used from libpq. This is
+ required for most external engines. Per report and initial code
+ from Lars Kanis.
+</p>
+
+<p>
+- In pgsql/src/backend/libpq/hba.c, parse_ident_usermap() should use
+ ereport(LOG) and not ERROR, and put the return value in the *error_p
+ variable. Noted by Tom Lane.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/client-auth.sgml, fix incorrect LDAP example,
+ noted by Tom Lane.
+</p>
+
+<p>
+- In pgsql/src/backend/libpq/auth.c, disallow empty passwords in LDAP
+ authentication, the same way we already do it for PAM.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- Disable pg_standby -l option because the backend doesn't expect the
+ recovered file to be a symlink. We tried to fix this issue with an
+ earlier server-side patch, but it didn't fix the whole issue. The
+ same bug is present in older releases as well, but the 8.4 train is
+ about to leave the station, and I'm not sure if have consensus on
+ whether we can remove the -l option in back-branches or do we need
+ to attempt a server-side fix to make symlinking safe. Patch by
+ Simon Riggs, per discussion on bug identified by Fujii Masao.
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/twophase.c, the code to unlink
+ dropped relations in FinishPreparedTransaction() was acting like
+ runs inside WAL recovery, but it doesn't. I must've copy-pasted
+ this from a redo-function in the relation forks patch. Noticed by
+ Tom Lane while he was looking through callers of smgrdounlink().
+</p>
+
+<p>
+- Fix some serious bugs in archive recovery, now that bgwriter is
+ active during it: When bgwriter is active, the startup process can't
+ perform mdsync() correctly because it won't see the fsync requests
+ accumulated in bgwriter's private pendingOpsTable. Therefore make
+ bgwriter responsible for the end-of-recovery checkpoint as well,
+ when it's active. When bgwriter is active (= archive recovery), the
+ startup process must not accumulate fsync requests to its own
+ pendingOpsTable, since bgwriter won't see them there when it
+ performs restartpoints. Make startup process drop its
+ pendingOpsTable when bgwriter is launched to avoid that. Update
+ minimum recovery point one last time when leaving archive recovery.
+ It won't be updated by the end-of-recovery checkpoint because
+ XLogFlush() sees us as out of recovery already. This fixes bug
+ #4879 reported by Fujii Masao.
