+<h2>Reviews</h2>
+<p>
+ITAGAKI Takahiro reviewed the per-column collation patch, bringing up
+issues with pg_dump, along with a couple of naming issues in the
+source code and a request for clearer global state.
+== Applied Patches ==
+</p>
+
+<p>
+Peter Eisentraut pushed:
+</p>
+
+<p>
+- Put only single space after "Sort Method:", for consistency.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=951d7861212120571a601d946194892db6f2bde1">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=951d7861212120571a601d946194892db6f2bde1</a>
+</p>
+
+<p>
+Heikki Linnakangas pushed:
+</p>
+
+<p>
+- Fix two typos, by Fujii Masao.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=95e42a2c2980003880dee622fc3bed0b03322542">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=95e42a2c2980003880dee622fc3bed0b03322542</a>
+</p>
+
+<p>
+- Fix bugs in the hot standby known-assigned-xids tracking logic. If
+ there's an old transaction running in the master, and a lot of
+ transactions have started and finished since, and a WAL-record is
+ written in the gap between the creating the running-xacts snapshot
+ and WAL-logging it, recovery will fail with "too many
+ KnownAssignedXids" error. This bug was reported by Joachim Wieland
+ on Nov 19th. In the same scenario, when fewer transactions have
+ started so that all the xids fit in KnownAssignedXids despite the
+ first bug, a more serious bug arises. We incorrectly initialize the
+ clog code with the oldest still running transaction, and when we see
+ the WAL record belonging to a transaction with an XID larger than
+ one that committed already before the checkpoint we're recovering
+ from, we zero the clog page containing the already committed
+ transaction, leading to data loss. In hindsight, trying to track
+ xids in the known-assigned-xids array before seeing the
+ running-xacts record was too complicated. To fix that, hold
+ XidGenLock while the running-xacts snapshot is taken and WAL-logged.
+ That ensures that no transaction can begin or end in that gap, so
+ that in recvoery we know that the snapshot contains all transactions
+ running at that point in WAL.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5a031a5556ff83b8a9646892715d7fef415b83c3">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5a031a5556ff83b8a9646892715d7fef415b83c3</a>
+</p>
+
+<p>
+Andrew Dunstan pushed:
+</p>
+
+<p>
+- Allow the low level COPY routines to read arbitrary numbers of
+ fields. This doesn't involve any user-visible change in behavior,
+ but will be useful when the COPY routines are exposed to allow their
+ use by Foreign Data Wrapper routines, which will be able to use
+ these routines to read irregular CSV files, for example.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=af1a614ec6d074fdea46de2e1c462f23fc7ddc6f">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=af1a614ec6d074fdea46de2e1c462f23fc7ddc6f</a>
+</p>
+
+<p>
+Tom Lane pushed:
+</p>
+
+<p>
+- Add a stack overflow check to copyObject(). There are some code
+ paths, such as SPI_execute(), where we invoke copyObject() on raw
+ parse trees before doing parse analysis on them. Since the bison
+ grammar is capable of building heavily nested parsetrees while
+ itself using only minimal stack depth, this means that copyObject()
+ can be the front-line function that hits stack overflow before
+ anything else does. Accordingly, it had better have a
+ check_stack_depth() call. I did a bit of performance testing and
+ found that this slows down copyObject() by only a few percent, so
+ the hit ought to be negligible in the context of complete processing
+ of a query. Per off-list report from Toshihide Katayama.
+ Back-patch to all supported branches.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8b5692809707c0e15d04c530a3fed9347350ea01">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8b5692809707c0e15d04c530a3fed9347350ea01</a>
+</p>
+
+<p>
+- Force default wal_sync_method to be fdatasync on Linux. Recent
+ versions of the Linux system header files cause xlogdefs.h to
+ believe that open_datasync should be the default sync method,
+ whereas formerly fdatasync was the default on Linux. open_datasync
+ is a bad choice, first because it doesn't actually outperform
+ fdatasync (in fact the reverse), and second because we try to use
+ O_DIRECT with it, causing failures on certain filesystems (e.g.,
+ ext4 with data=journal option). This part of the patch is largely
+ per a proposal from Marti Raudsepp. More extensive changes are
+ likely to follow in HEAD, but this is as much change as we want to
+ back-patch. Also clean up confusing code and incorrect
+ documentation surrounding the fsync_writethrough option. Those
+ changes shouldn't result in any actual behavioral change, but I
+ chose to back-patch them anyway to keep the branches looking similar
+ in this area. In 9.0 and HEAD, also do some copy-editing on the WAL
+ Reliability documentation section. Back-patch to all supported
+ branches, since any of them might get used on modern Linux versions.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=576477e73c4a9cb32c7471c1cec354fd5328140e">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=576477e73c4a9cb32c7471c1cec354fd5328140e</a>
+</p>
+
+<p>
+- Clean up some copied-and-pasted code in pg_upgrade. 1. Don't
+ reimplement S_ISDIR() and S_ISREG() badly. 2. Don't reimplement
+ access() badly. This code appears to have been copied from ancient
+ versions of the corresponding backend routines, and not patched to
+ incorporate subsequent fixes (see my commits of 2008-03-31 and
+ 2010-01-14 respectively). It might be a good idea to change it to
+ just *call* those routines, but for now I'll just transpose these
+ fixes over.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=663fc32e26e8df41434d751e2203c1aa410d1916">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=663fc32e26e8df41434d751e2203c1aa410d1916</a>
+</p>
+
+<p>
+- Make S_IRGRP etc available in mingw builds as well as MSVC. (Hm, I
+ wonder whether BCC defines them either...) Also label dangling
+ endifs a bit better in this area.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5132ad8bdf8e85ea0054217ef7ee38c51ace4824">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5132ad8bdf8e85ea0054217ef7ee38c51ace4824</a>
+</p>
+
+<p>
+- Reset all database-level stats in pgstat_recv_resetcounter(). We
+ were failing to zero out some pg_stat_database counters that have
+ been added since the initial pgstats coding. This is a bug, but not
+ back-patching the fix since changing this behavior in a minor
+ release seems a cure worse than the disease. Report and patch by
+ Tomas Vondra.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=0c90442355fbbe785740669f63141f24674c8958">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=0c90442355fbbe785740669f63141f24674c8958</a>

+Simon Riggs pushed:
+</p>
+
+<p>
+- Optimize commit_siblings in two ways to improve group commit.
+ First, avoid scanning the whole ProcArray once we know there are at
+ least commit_siblings active; second, skip the check altogether if
+ commit_siblings = 0. Greg Smith.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=e620ee35b249b0af255ef788003d1c9edb815a35">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=e620ee35b249b0af255ef788003d1c9edb815a35</a>
+</p>
+
+<p>
+- Reduce spurious Hot Standby conflicts from never-visible records.
+ Hot Standby conflicts only with tuples that were visible at some
+ point. So ignore tuples from aborted transactions or for tuples
+ updated/deleted during the inserting transaction when generating the
+ conflict transaction ids. Following detailed analysis and test case
+ by Noah Misch. Original report covered btree delete records,
+ correctly observed by Heikki Linnakangas that this applies to other
+ cases also. Fix covers all sources of cleanup records via common
+ code.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=b9075a6d2f9b07a00262a670dd60272904c79dce">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=b9075a6d2f9b07a00262a670dd60272904c79dce</a>

+
+<p>
+- Self review of previous patch. Fix assumption that xmax >= xmin.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9975c683b102d06ed5d5ab799eaba0d00a9ff38c">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9975c683b102d06ed5d5ab799eaba0d00a9ff38c</a>

+Robert Haas pushed:
+</p>
+
+<p>
+- Generalize concept of temporary relations to "relation persistence".
+ This commit replaces pg_class.relistemp with
+ pg_class.relpersistence; and also modifies the RangeVar node type to
+ carry relpersistence rather than istemp. It also removes removes
+ rd_istemp from RelationData and instead performs the correct
+ computation based on relpersistence. For clarity, we add three new
+ macros: RelationNeedsWAL(), RelationUsesLocalBuffers(), and
+ RelationUsesTempNamespace(), so that we can clarify the purpose of
+ each check that previous depended on rd_istemp. This is intended as
+ infrastructure for the upcoming unlogged tables patch, as well as
+ for future possible work on global temporary tables.

+</p>
+
+<p>
+- Allow plugins to suppress inlining and hook function
+ entry/exit/abort. This is intended as infrastructure to allow an
+ eventual SE-Linux plugin to support trusted procedures. KaiGai
+ Kohei.

+</p>
+
+<p>
+- Improved tab completion for views with triggers. Allow INSERT INTO,
+ UPDATE, and DELETE FROM to be completed with either the name of a
+ table (as before) or the name of a view with an appropriate INSTEAD
+ OF rule. Along the way, allow CREATE TRIGGER to be completed with
+ INSTEAD OF, as well as BEFORE and AFTER. David Fetter, reviewed by
+ Itagaki Takahiro

+- Document timestamptz a little better.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=afc8f47b5885716db716a2523c00f7465cb7f415">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=afc8f47b5885716db716a2523c00f7465cb7f415</a>

+</p>
+
+<p>
+- Waiting for complete startup is now a well-defined operation. Per
+ report from Fujii Masao, and subsequent discussion.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=df142bf82c84de5d0588ae7d52881501abb039ed">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=df142bf82c84de5d0588ae7d52881501abb039ed</a>
+</p>
+
+<p>
+- Reset 'ps' display just once when resolving VXID conflicts. This
+ prevents the word "waiting" from briefly disappearing from the ps
+ status line when ResolveRecoveryConflictWithVirtualXIDs begins a new
+ iteration of the outer loop. Along the way, remove some useless
+ pgstat_report_waiting() calls; the startup process doesn't appear in
+ pg_stat_activity. Fujii Masao.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=611fed371227f430e71d0ff7fed037f1006b410d">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=611fed371227f430e71d0ff7fed037f1006b410d</a>

+
+<p>
+- Try to save a kernel call in ResolveRecoveryConflictWithVirtualXIDs.
+ If there's no work to be done, just exit quickly, before initialization.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8bd4b89e240cc6488f5e1523202cc2d27e9970c0">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8bd4b89e240cc6488f5e1523202cc2d27e9970c0</a>

+
+<p>
+- Update time zone data files to tzdata release 2010o: DST law changes
+ in Fiji and Samoa. Historical corrections for Hong Kong.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f5e4f743e6a84884156ac86948277df4c672865c">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f5e4f743e6a84884156ac86948277df4c672865c</a>
+</p>
+
+<p>
+- Update release notes for releases 9.0.2, 8.4.6, 8.3.13, 8.2.19, and
+ 8.1.23.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f9224c8ec2f6dcfed6daa3f94597b870ec31c8d8">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f9224c8ec2f6dcfed6daa3f94597b870ec31c8d8</a>
+</p>
+
+<p>
+- Fix contrib/seg's GiST picksplit method. This patch replaces
+ Guttman's generalized split method with a simple
+ sort-by-center-points algorithm. Since the data is only
+ one-dimensional we don't really need the slow and none-too-stable
+ Guttman method. This is in part a bug fix, since seg has the same
+ size_alpha versus size_beta typo that was recently fixed in
+ contrib/cube. It seems prudent to apply this rather aggressive fix
+ only in HEAD, though. Back branches will just get the typo fix.
+ Alexander Korotkov, reviewed by Yeb Havinga.

+</p>
+
+<p>
+- Fix up getopt() reset management so it works on recent mingw. The
+ mingw people don't appear to care about compatibility with non-GNU
+ versions of getopt, so force use of our own copy of getopt on
+ Windows. Also, ensure that we make use of optreset when using our
+ own copy. Per report from Andrew Dunstan. Back-patch to all
+ versions supported on Windows.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5cdd65f3241ce10c66953228daef60df7b3966d1">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5cdd65f3241ce10c66953228daef60df7b3966d1</a>
+</p>
+
+<p>
+- Remove optreset from src/port/ implementations of getopt and
+ getopt_long. We don't actually need optreset, because we can easily
+ fix the code to ensure that it's cleanly restartable after having
+ completed a scan over the argv array; which is the only case we need
+ to restart in. Getting rid of it avoids a class of interactions
+ with the system libraries and allows reversion of my change of
+ yesterday in postmaster.c and postgres.c. Back-patch to 8.4.
+ Before that the getopt code was a bit different anyway.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=61b53695fbbedb7fa9d394e71bf2affdc494e6b0">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=61b53695fbbedb7fa9d394e71bf2affdc494e6b0</a>
+</p>
+
+<p>
+- Improve comments around startup_hacks() code. These comments were
+ not updated when we added the EXEC_BACKEND mechanism for Windows,
+ even though it rendered them inaccurate. Also unify two
+ unnecessarily-separate #ifdef __alpha code blocks.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=14ed7735f5bb5275da13891c4bb106c198d00b53">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=14ed7735f5bb5275da13891c4bb106c198d00b53</a>
+</p>
+
+<p>
+- Fix erroneous parsing of tsquery input "... & !(subexpression) |
+ ..." After parsing a parenthesized subexpression, we must pop all
+ pending ANDs and NOTs off the stack, just like the case for a simple
+ operand. Per bug #5793. Also fix clones of this routine in
+ contrib/intarray and contrib/ltree, where input of types query_int
+ and ltxtquery had the same problem. Back-patch to all supported
+ versions.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=abc10262696e53773c9a8c9f279bbd464b464190">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=abc10262696e53773c9a8c9f279bbd464b464190</a>
+</p>
+
+<p>
+- Fix up handling of simple-form CASE with constant test expression.
+ eval_const_expressions() can replace CaseTestExprs with constants
+ when the surrounding CASE's test expression is a constant. This
+ confuses ruleutils.c's heuristic for deparsing simple-form CASEs,
+ leading to Assert failures or "unexpected CASE WHEN clause" errors.
+ I had put in a hack solution for that years ago (see commit
+ 514ce7a331c5bea8e55b106d624e55732a002295 of 2006-10-01), but bug
+ #5794 from Peter Speck shows that that solution failed to cover all
+ cases. Fortunately, there's a much better way, which came to me
+ upon reflecting that Peter's "CASE TRUE WHEN" seemed pretty
+ redundant: we can "simplify" the simple-form CASE to the general
+ form of CASE, by simply omitting the constant test expression from
+ the rebuilt CASE construct. This is intuitively valid because there
+ is no need for the executor to evaluate the test expression at
+ runtime; it will never be referenced, because any CaseTestExprs that
+ would have referenced it are now replaced by constants. This won't
+ save a whole lot of cycles, since evaluating a Const is pretty
+ cheap, but a cycle saved is a cycle earned. In any case it beats
+ kluging ruleutils.c still further. So this patch improves
+ const-simplification and reverts the previous change in ruleutils.c.
+ Back-patch to all supported branches. The bug exists in 8.1 too,
+ but it's out of warranty.
