+<h2>Applied Patches</h2>
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- In pgsql/src/backend/optimizer/plan/setrefs.c, while doing the final
+  setrefs.c pass over a plan tree, try to match up non-Var sort/group
+  expressions using ressortgroupref labels instead of depending
+  entirely on equal()-ity of the upper node's tlist expressions to the
+  lower node's.  This avoids emitting the wrong outputs in cases where
+  there are textually identical volatile sort/group expressions, as
+  for example:
+  SELECT DISTINCT random(), random() FROM generate_series(1,10);
+  Per report from Andrew Gierth.  Backpatch to 8.4.  Arguably this is
+  wrong all the way back, but the only known case where there's an
+  observable problem is when using hash aggregation to implement
+  DISTINCT, which is new as of 8.4.  So for the moment I'll refrain
+  from backpatching further.
+</p>
+
+<p>
+- Provide a parenthesized-options syntax for VACUUM, analogous to that
+  recently adopted for EXPLAIN.  This will allow additional options to
+  be implemented in future without having to make them fully-reserved
+  keywords.  The old syntax remains available for existing options,
+  however.  Itagaki Takahiro
+</p>
+
+<p>
+- Add a hook to CREATE/ALTER ROLE to allow an external module to check
+  the strength of database passwords, and create a sample
+  implementation of such a hook as a new contrib module
+  "passwordcheck".  Laurenz Albe, reviewed by Takahiro Itagaki.
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster/syslogger.c, fix memory leak in
+  syslogger: logfile_rotate() would leak a copy of the output filename
+  if CSV logging was enabled and only one of the two possible output
+  files got rotated during a particular call (which would, in fact,
+  typically be the case during a size-based rotation).  This would
+  amount to about MAXPGPATH (1KB) per rotation, and it's been there
+  since the CSV code was put in, so it's surprising that nobody
+  noticed it before.  Per bug #5196 from Thomas Poindessous.
+</p>
+
+<p>
+- Add a WHEN clause to CREATE TRIGGER, allowing a boolean expression
+  to be checked to determine whether the trigger should be fired.  For
+  BEFORE triggers this is mostly a matter of spec compliance; but for
+  AFTER triggers it can provide a noticeable performance improvement,
+  since queuing of a deferred trigger event and re-fetching of the
+  row(s) at end of statement can be short-circuited if the trigger
+  does not need to be fired.  Takahiro Itagaki, reviewed by KaiGai
+  Kohei.
+</p>
+
+<p>
+- Fix display and dumping of UPDATE OR TRUNCATE triggers (a bizarre
+  combination maybe, but we should get it right).  Bug noted while
+  reviewing TRIGGER WHEN patch.  Already fixed in HEAD.
+</p>
+
+<p>
+- Refactor ecpg grammar so that it uses the core grammar's
+  unreserved_keyword list, minus a few specific words that have to be
+  treated specially.  This replaces a hard-wired list of keywords that
+  would have needed manual maintenance, and was not getting it.  The
+  8.4 coding was already missing these words, causing ecpg to
+  incorrectly treat them as reserved words: CALLED, CATALOG, DEFINER,
+  ENUM, FOLLOWING, INVOKER, OPTIONS, PARTITION, PRECEDING, RANGE,
+  SECURITY, SERVER, UNBOUNDED, WRAPPER.  In HEAD we were additionally
+  missing COMMENTS, FUNCTIONS, SEQUENCES, TABLES.  Per gripe from
+  Bosco Rama.
+</p>
+
+<p>
+- Improve psql's tabular display of wrapped-around data by inserting
+  markers in the formerly-always-blank columns just to left and right
+  of the data.  Different marking is used for a line break caused by a
+  newline in the data than for a straight wraparound.  A newline break
+  is signaled by a "+" in the right margin column in ASCII mode, or a
+  carriage return arrow in UNICODE mode.  Wraparound is signaled by a
+  dot in the right margin as well as the following left margin in
+  ASCII mode, or an ellipsis symbol in the same places in UNICODE
+  mode.  "\pset linestyle old-ascii" is added to make the previous
+  behavior available if anyone really wants it.  In passing, this
+  commit also cleans up a few regression test files that had
+  unintended spacing differences from the current actual output.
+  Roger Leigh, reviewed by Gabrielle Roth and other members of PDXPUG.
+</p>
+
+<p>
+- In pgsql/src/test/regress/expected/xmlmap.out, ooops, forgot to
+  check the libxml cases for psql output wrapping change.
+</p>
+
+<p>
+- In pgsql/src/test/regress/pg_regress.c, remove -w
+  (--ignore-all-space) option from pg_regress's diff calls.  We have
+  used -w for a long time as a means of reducing the reported diff
+  volume when one element of a result table isn't of the expected
+  width.  However, most of the time the results just pass anyway, so
+  this isn't as important as it once was.  Meanwhile, the risk of
+  missing potentially significant deviations has gone up, particularly
+  with psql's ability to report error cursor positions.  So, let's
+  switch over to space-sensitive comparisons.  Per my proposal of
+  yesterday.  (All the expected files that I can test here seem to be
+  ready for this already, but we'll see what the buildfarm thinks
+  about others.)
+</p>
+
+<p>
+- In pgsql/src/test/regress/output/largeobject_1.source, adjust
+  expected-results spacing per buildfarm results.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/psql-ref.sgml, assorted wordsmithing on
+  the documentation of \pset --- try to make it a bit more consistent
+  and less obviously written by different people at different times.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/src/bin/pg_dump/pg_restore.c, typo: dump -> restore.  Fixed
+  in 8.4 and 8.5 Author: Guillaume Lelarge <guillaume@lelarge.info>
+</p>
+
+<p>
+- In pgsql/src/bin/psql/mainloop.c, ignore UTF-8-encoded Unicode
+  byte-order mark at the beginning of a file if the client encoding is
+  UTF-8.  A limited version of a patch proposed by Itagaki Takahiro
+</p>
+
+<p>
+Magnus Hagander committed:
+</p>
+
+<p>
+- Revert backpatch of inheritable-ACE patch for Win32, since it broke
+  compatibility with pre-Windows 2000 versions.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- In pgsql/src/backend/optimizer/path/allpaths.c, remove superfluous
+  curly brace, fixing compilation with OPTIMIZER_DEBUG.  Jan Urbanski.
+</p>
