+<h2>Reviews</h2>
+<h2>Applied Patches</h2>
+<p>
+Alvaro Herrera pushed:
+</p>
+
+<p>
+- Duplicate expansion of "direction" from FETCH's synopsis into MOVE
+  <a href="http://git.postgresql.org/pg/commitdiff/8c250f3741f4f897362de32a03f56726cf3f9774">http://git.postgresql.org/pg/commitdiff/8c250f3741f4f897362de32a03f56726cf3f9774</a>
+</p>
+
+<p>
+- Uppercase <!ENTITY> and <!DOCTYPE> tags in SGML source.  This
+  improves compatibility with external toolchains, such as those used
+  by some documentation translation tools.  Gabriele Bartolini
+  <a href="http://git.postgresql.org/pg/commitdiff/fc3459d70c5d842fe6519522649c8a47454f25bb">http://git.postgresql.org/pg/commitdiff/fc3459d70c5d842fe6519522649c8a47454f25bb</a>
+</p>
+
+<p>
+- Update MSVC toolchain to match SGML entity uppercasing.  Per Robert
+  Haas
+  <a href="http://git.postgresql.org/pg/commitdiff/34a991619bddf2bfb441cf2d4396b67198326bcd">http://git.postgresql.org/pg/commitdiff/34a991619bddf2bfb441cf2d4396b67198326bcd</a>
+</p>
+
+<p>
+- Change "Id" to "id" in some SGML tags.  Gabriele Bartolini
+  <a href="http://git.postgresql.org/pg/commitdiff/38d15f16511cb9f75ed2b1e1f73117c1bc581538">http://git.postgresql.org/pg/commitdiff/38d15f16511cb9f75ed2b1e1f73117c1bc581538</a>
+</p>
+
+<p>
+Robert Haas pushed:
+</p>
+
+<p>
+- Include pid in pg_lock_status() results even for SIREAD locks.  Dan
+  Ports.
+  <a href="http://git.postgresql.org/pg/commitdiff/a0e50e698beb89a8ec203303581e464a5f69fc41">http://git.postgresql.org/pg/commitdiff/a0e50e698beb89a8ec203303581e464a5f69fc41</a>
+</p>
+
+<p>
+- Add missing check on invocation of trusted procedures.  KaiGai Kohei
+  <a href="http://git.postgresql.org/pg/commitdiff/595a441ae999fb155a381fa4bcceadf40f041a33">http://git.postgresql.org/pg/commitdiff/595a441ae999fb155a381fa4bcceadf40f041a33</a>
+</p>
+
+<p>
+- Merge synchronous_replication setting into synchronous_commit.  This
+  means one less thing to configure when setting up synchronous
+  replication, and also avoids some ambiguity around what the behavior
+  should be when the settings of these variables conflict.  Fujii
+  Masao, with additional hacking by me.
+  <a href="http://git.postgresql.org/pg/commitdiff/240067b3b0ff989d2b28f4f917f7958f2ec76b05">http://git.postgresql.org/pg/commitdiff/240067b3b0ff989d2b28f4f917f7958f2ec76b05</a>
+</p>
+
+<p>
+- Add casts from int4 and int8 to numeric.  Joey Adams, per gripe from
+  Ramanujam.  Review by myself and Tom Lane.
+  <a href="http://git.postgresql.org/pg/commitdiff/f5e524d92be609c709825be8995bf77f10880c3b">http://git.postgresql.org/pg/commitdiff/f5e524d92be609c709825be8995bf77f10880c3b</a>
+</p>
+
+<p>
+- Typo fixes.  Erik Rijkers
+  <a href="http://git.postgresql.org/pg/commitdiff/ad275473a5ea75f4aa010791884004f75f3c7a65">http://git.postgresql.org/pg/commitdiff/ad275473a5ea75f4aa010791884004f75f3c7a65</a>
+</p>
+
+<p>
+- Repair some flakiness in CheckTargetForConflictsIn.  When we release
+  and reacquire SerializableXactHashLock, we must recheck whether an
+  R/W conflict still needs to be flagged, because it could have
+  changed under us in the meantime.  And when we release the partition
+  lock, we must re-walk the list of predicate locks from the
+  beginning, because our pointer could get invalidated under us.  Bug
+  report #5952 by Yamamoto Takashi.  Patch by Kevin Grittner.
+  <a href="http://git.postgresql.org/pg/commitdiff/632f0faa7c975e8984ce0f1d6b631478e41a96c2">http://git.postgresql.org/pg/commitdiff/632f0faa7c975e8984ce0f1d6b631478e41a96c2</a>
+</p>
+
+<p>
+- Fix some sloppiness in new PL/python get_source_line() function.
+  Jan Urbański
+  <a href="http://git.postgresql.org/pg/commitdiff/b6bc481d5540a3ad0d39db1e9881e6bd52e54213">http://git.postgresql.org/pg/commitdiff/b6bc481d5540a3ad0d39db1e9881e6bd52e54213</a>
+</p>
+
+<p>
+- Partially roll back overenthusiastic SSI optimization.  When a
+  regular lock is held, Steve Singer can use that in lieu of a
+  predicate lock to detect rw conflicts; but if the regular lock is
+  being taken by a subtransaction, we can't assume that it'll commit,
+  so releasing the parent transaction's lock in that case is a no-no.
+  Kevin Grittner
+  <a href="http://git.postgresql.org/pg/commitdiff/fbc0d07796bcae8b2ee4b09ed236877338c95130">http://git.postgresql.org/pg/commitdiff/fbc0d07796bcae8b2ee4b09ed236877338c95130</a>
+</p>
+
+<p>
+- Fix bug in propagating ALTER TABLE actions to typed tables.  We need
+  to propagate such actions to all typed table children of a given
+  type, not just the first one.  Noah Misch
+  <a href="http://git.postgresql.org/pg/commitdiff/0bd155cbf2543cdead70b6e6390e9260035e1468">http://git.postgresql.org/pg/commitdiff/0bd155cbf2543cdead70b6e6390e9260035e1468</a>
+</p>
+
+<p>
+- Make psql use pg_table_size instead of pg_relation_size on 9.0+
+  servers.  Per discussion, pg_table_size() is a more helpful number
+  than pg_relation_size().  Bernd Helmle, reviewed by Susanne Ebrecht
+  and me.
+  <a href="http://git.postgresql.org/pg/commitdiff/cba9cd419270a9b7f442877e21685ac0de5730b3">http://git.postgresql.org/pg/commitdiff/cba9cd419270a9b7f442877e21685ac0de5730b3</a>
+</p>
+
+<p>
+- Truncate the predicate lock SLRU to empty, instead of almost empty.
+  Otherwise, the SLRU machinery can get confused and think that the
+  SLRU has wrapped around.  Along the way, regardless of whether we're
+  truncating all of the SLRU or just some of it, flush pages after
+  truncating, rather than before.  Kevin Grittner
+  <a href="http://git.postgresql.org/pg/commitdiff/cdcdfca40199bbdb30c78d105e4db267b631289c">http://git.postgresql.org/pg/commitdiff/cdcdfca40199bbdb30c78d105e4db267b631289c</a>
+</p>
+
+<p>
+Simon Riggs pushed:
+</p>
+
+<p>
+- Update comments and credit doc proofreaders
+  <a href="http://git.postgresql.org/pg/commitdiff/35d2a660fea51f8acae6aa0895875757fa09cb26">http://git.postgresql.org/pg/commitdiff/35d2a660fea51f8acae6aa0895875757fa09cb26</a>
+</p>
+
+<p>
+- Centralise release note items related to recovery and replication
+  <a href="http://git.postgresql.org/pg/commitdiff/479ee1b962ca2d479310af762c21d7c2056fdeca">http://git.postgresql.org/pg/commitdiff/479ee1b962ca2d479310af762c21d7c2056fdeca</a>
+</p>
+
+<p>
+- Avoid assuming there will be only 3 states for synchronous_commit.
+  Also avoid hardcoding the current default state by giving it the
+  name "on" and replace with a meaningful name that reflects its
+  behaviour.  Coding only, no change in behaviour.
+  <a href="http://git.postgresql.org/pg/commitdiff/88f32b7ca29982f286b61a9d0dd29be4b8a01c25">http://git.postgresql.org/pg/commitdiff/88f32b7ca29982f286b61a9d0dd29be4b8a01c25</a>
+</p>
+
+<p>
+Peter Eisentraut pushed:
+</p>
+
+<p>
+- Update key words table for 9.1
+  <a href="http://git.postgresql.org/pg/commitdiff/bf6848bc8c82e82f857d48185554bc3e6dcf1013">http://git.postgresql.org/pg/commitdiff/bf6848bc8c82e82f857d48185554bc3e6dcf1013</a>
+</p>
+
+<p>
+- Add traceback information to PL/Python errors.  This mimics the
+  traceback information the Python interpreter prints with exceptions.
+  Jan Urbański
+  <a href="http://git.postgresql.org/pg/commitdiff/2bd78eb8d51cc9ee03ba0287b23ff4c266dcd9b9">http://git.postgresql.org/pg/commitdiff/2bd78eb8d51cc9ee03ba0287b23ff4c266dcd9b9</a>
+</p>
+
+<p>
+- Replace the confusing exit_nicely() by an atexit/on_exit hook
+  <a href="http://git.postgresql.org/pg/commitdiff/c75163842cf93fd7b6311df2c5545bf09447b870">http://git.postgresql.org/pg/commitdiff/c75163842cf93fd7b6311df2c5545bf09447b870</a>
+</p>
+
+<p>
+- Update regression test files for PL/Python traceback patch.
+  <a href="http://git.postgresql.org/pg/commitdiff/5d0e462366f4521e37744fdb42fed3c6819a3374">http://git.postgresql.org/pg/commitdiff/5d0e462366f4521e37744fdb42fed3c6819a3374</a>
+</p>
+
+<p>
+- Allow pg_upgrade with PGCLIENTENCODING set.  This used to work, but
+  since PGCLIENTENCODING is now a connection option variable,
+  pg_upgrade would prevent it.
+  <a href="http://git.postgresql.org/pg/commitdiff/1eb2231fc46bbfa85b47c19d88f72162b323aa51">http://git.postgresql.org/pg/commitdiff/1eb2231fc46bbfa85b47c19d88f72162b323aa51</a>
+</p>
+
+<p>
+- Add collation support on Windows (MSVC build).  There is not yet
+  support in initdb to populate the pg_collation catalog, but if that
+  is done manually, the rest should work.
+  <a href="http://git.postgresql.org/pg/commitdiff/11745364d074f3a7ee54c98fad55cfb5c5149326">http://git.postgresql.org/pg/commitdiff/11745364d074f3a7ee54c98fad55cfb5c5149326</a>
+</p>
+
+<p>
+Tom Lane pushed:
+</p>
+
+<p>
+- Revise the API for GUC variable assign hooks.  The previous
+  functions of assign hooks are now split between check hooks and
+  assign hooks, where the former can fail but the latter shouldn't.
+  Aside from being conceptually clearer, this approach exposes the
+  "canonicalized" form of the variable value to guc.c without having
+  to do an actual assignment.  And that lets us fix the problem
+  recently noted by Bernd Helmle that the auto-tune patch for
+  wal_buffers resulted in bogus log messages about "parameter
+  "wal_buffers" cannot be changed without restarting the server".
+  There may be some speed advantage too, because this design lets hook
+  functions avoid re-parsing variable values when restoring a previous
+  state after a rollback (they can store a pre-parsed representation
+  of the value instead).  This patch also resolves a longstanding
+  annoyance about custom error messages from variable assign hooks:
+  they should modify, not appear separately from, guc.c's own message
+  about "invalid parameter value".
+  <a href="http://git.postgresql.org/pg/commitdiff/2594cf0e8c04406ffff19b1651c5a406d376657c">http://git.postgresql.org/pg/commitdiff/2594cf0e8c04406ffff19b1651c5a406d376657c</a>
+</p>
+
+<p>
+- Fix collations when we call transformWhereClause from outside the
+  parser.  Previous patches took care of assorted places that call
+  transformExpr from outside the main parser, but I overlooked the
+  fact that some places use transformWhereClause as a shortcut for
+  transformExpr + coerce_to_boolean.  In particular this broke
+  collation-sensitive index WHERE clauses, as per report from Thom
+  Brown.  Trigger WHEN and rule WHERE clauses too.  I'm not forcing
+  initdb for this fix, but any affected indexes, triggers, or rules
+  will need to be dropped and recreated.
+  <a href="http://git.postgresql.org/pg/commitdiff/d8d429890d6aa0246e28faa187a55cb0c65efd6e">http://git.postgresql.org/pg/commitdiff/d8d429890d6aa0246e28faa187a55cb0c65efd6e</a>
+</p>
+
+<p>
+- Fix SortTocFromFile() to cope with lines that are too long for its
+  buffer.  The original coding supposed that a dump TOC file could
+  never contain lines longer than 1K.  The folly of that was exposed
+  by a recent report from Per-Olov Esgard.  We only really need to see
+  the first dozen or two bytes of each line, since we're just trying
+  to read off the numeric ID at the start of the line; so there's no
+  need for a particularly huge buffer.  What there is a need for is
+  logic to not process continuation bufferloads.  Back-patch to all
+  supported branches, since it's always been like this.
+  <a href="http://git.postgresql.org/pg/commitdiff/1471a147f09f737511945ac59ca3162469d1a0c0">http://git.postgresql.org/pg/commitdiff/1471a147f09f737511945ac59ca3162469d1a0c0</a>
+</p>
+
+<p>
+- Fix plpgsql's issues with dropped columns in rowtypes in 8.4 branch.
+  This is a back-patch of commit dcb2bda9b7042dbf43f876c94ebf35d951de10e9
+  of Aug 6 2009, which fixed assorted cases in which plpgsql would
+  fail to cope with composite types that contain any dropped columns.
+  Per discussion, this fix has been out in 9.0 for long enough to make
+  it improbable that it creates any new bugs, so this is a low-risk
+  fix.  To make it even lower risk, I did not back-patch the changes
+  in execQual.c, but just accepted the duplication of code between

+- Modernize dlopen interface code for FreeBSD and OpenBSD.  Remove the
+  hard-wired assumption that __mips__ (and only __mips__) lacks dlopen
+  in FreeBSD and OpenBSD.  This assumption is outdated at least for
+  OpenBSD, as per report from an anonymous 9.1 tester.  We can
+  perfectly well use HAVE_DLOPEN instead to decide which code to use.
+  Some other cosmetic adjustments to make freebsd.c, netbsd.c, and
+  openbsd.c exactly alike.

+- Tweaks for SSI out-of-shared memory behavior.  If we call
+  hash_search() with HASH_ENTER, it will bail out rather than return
+  NULL, so it's redundant to check for NULL again in the caller.
+  Thus, in cases where we believe it's impossible for the hash table
+  to run out of slots anyway, we can simplify the code slightly.  On
+  the flip side, in cases where it's theoretically possible to run out
+  of space, we don't want to rely on dynahash.c to throw an error;
+  instead, we pass HASH_ENTER_NULL and throw the error ourselves if a
+  NULL comes back, so that we can provide a more descriptive error
+  message.  Kevin Grittner

+- Add an example of WITH (UPDATE RETURNING) INSERT to the INSERT ref
+  page.  Per a discussion with Gavin Flower.  This barely scratches
+  the surface of potential WITH (something RETURNING) use cases, of
+  course, but it's one of the simplest compelling examples I can think
+  of.

+- Avoid extra whitespace in the arguments of <indexterm>.  As noted by
+  Thom Brown, this confuses the DocBook index processor; it fails to
+  merge entries that differ only in whitespace, and sorts them
+  unexpectedly as well.  Seems like a toolchain bug, but I'm not going
+  to hold my breath waiting for a fix.  Note: easiest way to find
+  these is to look for double spaces in HTML.index.

+- Modify initdb to complain only when no usable system locales are
+  found.  Per discussion, the original behavior seems too noisy.  But
+  if things are so broken that none of the locales reported by
+  "locale -a" are usable, that's probably worth warning about.

+- Avoid an unnecessary syscache lookup in parse_coerce.c.  All the
+  other fields of the constant are being extracted from the syscache
+  entry we already have, so handle collation similarly.  (There don't
+  seem to be any other uses for the new function at the moment.)

+- Tweak collation setup for GIN index comparison functions.  Honor
+  index column's collation spec if there is one, don't go to the
+  expense of calling get_typcollation when we can reasonably assume
+  that all GIN storage types will use default collation, and be sure
+  to set a collation for the comparePartialFn too.

+- Fix make_greater_string to not have an undocumented collation
+  assumption.  The previous coding worked only if ltproc->fn_collation
+  was always either DEFAULT_COLLATION_OID or a C-compatible locale.
+  While that's true at the moment, it wasn't documented (and in fact
+  wasn't true when this code was committed...).  But it only takes a
+  couple more lines to make its internal caching behavior
+  locale-aware, so let's do that.

+- Clean up minor collation issues in indxpath.c.  Get rid of bogus
+  collation test in match_special_index_operator (even for ILIKE, the
+  pattern match operator's collation doesn't matter here, and even if
+  it did the test was testing the wrong thing).  Fix broken looping
+  logic in expand_indexqual_rowcompare.  Add collation check in
+  match_clause_to_ordering_op.  Make naming and argument ordering more
+  consistent; improve comments.

+- Don't show unusable collations in psql's \dO command.  "Unusable"
+  collations are those not matching the current database's encoding.
+  The former behavior inconsistently showed such collations some of
+  the time, depending on the details of the pattern argument.

+
+<p>
+- Adjust collation determination rules as per discussion.  Remove
+  crude hack that tried to propagate collation through a
+  function-returning-record, ie, from the function's arguments to
+  individual fields selected from its result record.  That is just
+  plain inconsistent, because the function result is composite and
+  cannot have a collation; and there's no hope of making this kind of
+  action-at-a-distance work consistently.  Adjust regression test
+  cases that expected this to happen.  Meanwhile, the behavior of
+  casting to a domain with a declared collation stays the same as it
+  was, since that seemed to be the consensus.

+<p>
+- Remove collate.linux.utf8.sql's assumptions about ".utf8" in locale
+  names.  Tweak the test so that it does not depend on the platform
+  using ".utf8" as the extension signifying that a locale uses UTF8
+  encoding.  For the most part this just requires using the
+  abbreviated collation names "en_US" etc, though I had to work a bit
+  harder on the collation creation tests.  This opens the door to
+  using the test on platforms that spell locales differently, for
+  example ".utf-8" or ".UTF-8".  Also, the test is now somewhat useful
+  with server encodings other than UTF8; though depending on which
+  encoding is selected, different subsets of it will fail for lack of
+  character set support.

+- Fix ILIKE to honor collation when working in single-byte encodings.
+  The original collation patch only fixed the multi-byte code path.
+  This change also ensures that ILIKE's idea of the case-folding rules
+  is exactly the same as str_tolower's.

+- Clean up overly complex code for issuing some related error
+  messages.  The original version was unreadable, and not mechanically
+  checkable either.

+
+<p>
+- Teach regular expression operators to honor collations.  This
+  involves getting the character classification and case-folding
+  functions in the regex library to use the collations infrastructure.
+  Most of this work had been done already in connection with the
+  upper/lower and LIKE logic, so it was a simple matter of
+  transposition.  While at it, split out these functions into a
+  separate source file regc_pg_locale.c, so that they can be correctly
+  labeled with the Postgres project's license rather than the
+  Scriptics license.  These functions are 100% Postgres-written code
+  whereas what remains in regc_locale.c is still mostly not ours, so
+  lumping them both under the same copyright notice was getting more
+  and more misleading.
