+<h2>Applied Patches</h2>
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- In pgsql/src/backend/utils/time/tqual.c, add summarization comment
+ about visibility functions. Add URL about the Halloween problem.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/monitoring.sgml, doc patch for the recently
+ added probes. Robert Lor
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- Accept 'on' and 'off' as input for boolean data type, unifying the
+ syntax that the data type and GUC accepts. ITAGAKI Takahiro
+</p>
+
+<p>
+- Tweak the regression test case so that the ordering of numbers vs.
+ letters doesn't matter. This fixes failures in the Czech locale.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/adt/bool.c, in parse_bool_with_len, avoid
+ crash when no result pointer is passed. Probably an unlikely call
+ mode, but better be safe.
+</p>
+
+<p>
+- In pgsql/src/backend/po/ru.po, translation updates.
+</p>
+
+<p>
+Teodor Sigaev committed:
+</p>
+
+<p>
+- In pgsql/src/backend/tsearch/wparser_def.c, prevent recursion during
+ parse of email-like string with multiple '@'. Patch by Heikki
+ Linnakangas.
+</p>
+
+<p>
+- In pgsql/src/backend/tsearch/wparser_def.c, some languages have
+ symbols with zero display's width or/and vowels/signs which are not
+ an alphabetic character although they are not word-breakers too.
+ So, treat them as part of word. Per off-list discussion with
+ Dibyendra Hyoju and and Bal Krishna Bal about the Nepali language
+ and Devanagari alphabet.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Fix set_subquery_pathlist() to copy the RTE's subquery before it
+ gets mangled by the planning process. This prevents the "failed to
+ locate grouping columns" error recently reported by Dickson Guedes.
+ That happens because planning replaces SubLinks by SubPlans in the
+ subquery's targetlist, and exprTypmod() is smarter about the former
+ than the latter, causing the apparent type of the subquery's output
+ columns to change. This seems to be a deficiency we should fix in
+ exprTypmod(), but that will be a much more invasive patch with
+ possible side-effects elsewhere, so I'll do that only in HEAD.
+ Back-patch to 8.3. Arguably the lack of a copying step is
+ broken/dangerous all the way back, but in the absence of known
+ problems I'll refrain from making the older branches pay the extra
+ cost. (The reason this particular symptom didn't appear before is
+ that exprTypmod() wasn't smart about SubLinks either, until 8.3.)
+</p>
+
+<p>
+- Make SubPlan nodes carry the result's typmod as well as datatype
+ OID. This is for consistency with the (relatively) recent addition
+ of typmod to SubLink. An example of why it's a good idea is to be
+ seen in the recent "failed to locate grouping columns" bug, which
+ wouldn't have happened if a SubPlan exposed the same typmod info as
+ the SubLink it was derived from. This could be back-patched, since
+ it doesn't affect any on-disk data format, but for the moment it
+ doesn't seem necessary to do so.
+</p>
+
+<p>
+- In pgsql/src/backend/optimizer/path/indxpath.c, improve
+ match_special_index_operator() to recognize that LIKE with an
+ exact-match pattern (no wildcard) can be index-optimized in some
+ cases where a prefix-match pattern cannot; specifically, since the
+ required index clause is simple equality, it works for regular
+ text/varchar indexes even when the locale is not C. I'm not sure
+ how often this case really comes up, but since it requires hardly
+ any additional work to handle it, we might as well get it right.
+ Motivated by a discussion on the JDBC list.
+</p>
+
+<p>
+- Code review for dtrace probes added (so far) to 8.4. Adjust
+ placement of some bufmgr probes, take out redundant and
+ memory-leak-inducing path arguments to smgr__md__read__done and
+ smgr__md__write__done, fix bogus attempt to recalculate space used
+ in sort__done, clean up formatting in places where I'm not sure
+ pgindent will do a nice job by itself.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/adt/formatting.c, fix core dump due to
+ null-pointer dereference in to_char() when datetime format codes are
+ misapplied to a numeric argument. (The code still produces a pretty
+ bogus error message in such cases, but I'll settle for stopping the
+ crash for now.) Per bug #4700 from Sergey Burladyan. Problem
+ exists in all supported branches, so patch all the way back. In
+ HEAD, also clean up some ugly coding in the nearby cache management
+ code.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, update back-branch release
+ notes.
+</p>
+
+<p>
+- In pgsql/src/backend/storage/buffer/bufmgr.c, restore previous
+ ordering of BUFFER_FLUSH_START probe. I had wanted to make it
+ include the time for the possible smgropen() call, but that results
+ in a null pointer dereference :-(. An alternative solution would be
+ to fetch the buffer tag instead of looking at *reln, but I'll just
+ put it back as it was for the moment. BTW, this indicates that
+ DTrace probes evaluate their arguments even when nominally inactive.
+ What was that about "zero cost", again?
+</p>
+
+<p>
+- In pgsql/src/bin/pg_dump/pg_backup_archiver.c, fix
+ identify_locking_dependencies to reflect the fact that
+ fix_dependencies previously repointed TABLE dependencies to TABLE
+ DATA. Mea culpa.
+</p>
+
+<p>
+- Clean up the code for to_timestamp's conversion of year plus ISO day
+ number to date, as per bug #4702 and subsequent discussion. In
+ particular, make it work for years specified using AD/BC or CC
+ fields, and fix the test for "no year specified" so that it doesn't
+ trigger inappropriately for 1 Bryce Cutt (which it was doing even in
+ code paths that had nothing to do with to_timestamp). I also did
+ some minor code beautification in the non-ISO-day-number code path.
+ This area has been busted all along, but because the code has been
+ rewritten repeatedly, it would be considerable trouble to
+ back-patch. It's such a corner case that it doesn't seem worth the
+ effort.
+</p>
+
+<p>
+- Fix contrib/hstore to throw an error for keys or values that don't
+ fit in its data structure, rather than silently truncating them.
+ Andrew Gierth.
+</p>
+
+<p>
+Alvaro Herrera committed:
+</p>
+
+<p>
+- Remove pg_trace.h inclusion from c.h and add it to the .c files that
+ need it. Only needed in 8.3 because it's already this way in HEAD,
+ and older branches did not support DTrace. This allows external
+ modules to compile on Linux machines where SystemTap support was
+ recently added, when the required SystemTap headers are not present
+ on the build machine. Approach suggested by Tom Lane, after a RPM
+ build trouble report by Devrim Gunduz.
+</p>
+
+<p>
+Andrew Dunstan committed:
+</p>
+
+<p>
+- Use thread-local storage for querybuffer in fmtId() on Windows, when
+ needed (i.e. when running pg_restore, which might run in parallel).
+ Only reopen archive file when we really need to read from it, in
+ parallel code. Otherwise, close it immediately in a worker, if
+ possible.
+</p>
+
+<p>
+Marc Fournier committed:
+</p>
+
+<p>
+- Tag 8.3.7, 8.2.13, 8.1.17, 8.0.21, and 7.4.25.
