+<h2>Reviews</h2>
+<h2>Applied Patches</h2>
+<p>
+Tom Lane pushed:
+</p>
+
+<p>
+- Fix unsafe order of operations in foreign-table DDL commands.  When
+  updating or deleting a system catalog tuple, it's necessary to
+  acquire RowExclusiveLock on the catalog before looking up the tuple;
+  otherwise a concurrent VACUUM FULL on the catalog might move the
+  tuple to a different TID before we can apply the update.  Coding
+  patterns that find the tuple via a table scan aren't at risk here,
+  but when obtaining the tuple from a catalog cache, correct ordering
+  is important; and several routines in foreigncmds.c got it wrong.
+  Noted while running the regression tests in parallel with VACUUM
+  FULL of assorted system catalogs.  For consistency I moved all the
+  heap_open calls to the starts of their functions, including a couple
+  for which there was no actual bug.  Back-patch to 8.4 where
+  foreigncmds.c was added.
+  <a href="http://git.postgresql.org/pg/commitdiff/52994e9e5686b10a92bc93ec0f4e15c7fbc18242">http://git.postgresql.org/pg/commitdiff/52994e9e5686b10a92bc93ec0f4e15c7fbc18242</a>
+</p>
+
+<p>
+- Fix race condition in relcache init file invalidation.  The previous
+  code tried to synchronize by unlinking the init file twice, but that
+  doesn't actually work: it leaves a window wherein a third process
+  could read the already-stale init file but miss the SI messages that
+  would tell it the data is stale.  The result would be bizarre
+  failures in catalog accesses, typically "could not read block 0 in
+  file ..." later during startup.  Instead, hold RelCacheInitLock
+  across both the unlink and the sending of the SI messages.  This is
+  more straightforward, and might even be a bit faster since only one
+  unlink call is needed.  This has been wrong since it was put in (in
+  2002!), so back-patch to all supported releases.
+  <a href="http://git.postgresql.org/pg/commitdiff/2ada6779c5d3fcc31568ba263f8a0cc9bb8318c1">http://git.postgresql.org/pg/commitdiff/2ada6779c5d3fcc31568ba263f8a0cc9bb8318c1</a>
+</p>
+
+<p>
+- Preserve toast value OIDs in toast-swap-by-content for
+  CLUSTER/VACUUM FULL.  This works around the problem that a catalog
+  cache entry might contain a toast pointer that we try to dereference
+  just as a VACUUM FULL completes on that catalog.  We will see the
+  sinval message on the cache entry when we acquire lock on the toast
+  table, but by that point we've already told tuptoaster.c "here's the
+  pointer to fetch", so it's difficult from a code structural
+  standpoint to update the pointer before we use it.  Much less
+  painful to ensure that toast pointers are not invalidated in the
+  first place.  We have to add a bit of code to deal with the case
+  that a value that previously wasn't toasted becomes so; but that
+  should be a seldom-exercised corner case, so the inefficiency
+  shouldn't be significant.  Back-patch to 9.0.  In prior versions, we
+  didn't allow CLUSTER on system catalogs, and VACUUM FULL didn't
+  result in reassignment of toast OIDs, so there was no problem.
+  <a href="http://git.postgresql.org/pg/commitdiff/7b0d0e9356963d5c3e4d329a917f5fbb82a2ef05">http://git.postgresql.org/pg/commitdiff/7b0d0e9356963d5c3e4d329a917f5fbb82a2ef05</a>
+</p>
+
+<p>
+- Fix incorrect order of operations during sinval reset processing.
+  We have to be sure that we have revalidated each nailed-in-cache
+  relcache entry before we try to use it to load data for some other
+  relcache entry.  The introduction of "mapped relations" in 9.0 broke
+  this, because although we updated the state kept in relmapper.c
+  early enough, we failed to propagate that information into relcache
+  entries soon enough; in particular, we could try to fetch pg_class
+  rows out of pg_class before we'd updated its relcache entry's
+  rd_node.relNode value from the map.  This bug accounts for Dave
+  Gould's report of failures after "vacuum full pg_class", and I
+  believe that there is risk for other system catalogs as well.  The
+  core part of the fix is to copy relmapper data into the relcache
+  entries during "phase 1" in RelationCacheInvalidate(), before
+  they'll be used in "phase 2".  To try to future-proof the code
+  against other similar bugs, I also rearranged the order in which
+  nailed relations are visited during phase 2: now it's pg_class
+  first, then pg_class_oid_index, then other nailed relations.  This
+  should ensure that RelationClearRelation can apply
+  RelationReloadIndexInfo to all nailed indexes without risking use of
+  not-yet-revalidated relcache entries.  Back-patch to 9.0 where the
+  relation mapper was introduced.
+  <a href="http://git.postgresql.org/pg/commitdiff/f4d7f1adbae831a37686d28cc5f89f0fcff48a54">http://git.postgresql.org/pg/commitdiff/f4d7f1adbae831a37686d28cc5f89f0fcff48a54</a>
+</p>
+
+<p>
+- Forget about targeting catalog cache invalidations by tuple TID.
+  The TID isn't stable enough: we might queue an sinval event before a
+  VACUUM FULL, and then process it afterwards, when the target tuple
+  no longer has the same TID.  So we must invalidate entries on the
+  basis of hash value only.  The old coding can be shown to result in
+  various bizarre, hard-to-reproduce errors in the presence of
+  concurrent VACUUM FULLs on system catalogs, and could easily result
+  in permanent catalog corruption, up to and including complete loss
+  of tables.  This commit is just a minimal fix that removes the
+  unsafe comparison.  We should remove transmission of the tuple TID
+  from sinval messages altogether, and then arrange to suppress the
+  extra message in the common case of a heap_update that doesn't
+  change the key hashvalue.  But that's going to be much more
+  invasive, and will only produce a probably-marginal performance
+  gain, so it doesn't seem like material for a back-patch.  Back-patch
+  to 9.0.  Before that, VACUUM FULL refused to do any tuple moving if
+  it found any INSERT_IN_PROGRESS or DELETE_IN_PROGRESS tuples (and
+  CLUSTER would give up altogether), so there was no risk of moving a
+  tuple that might be the subject of an unsent sinval message.
+  <a href="http://git.postgresql.org/pg/commitdiff/632ae6829f7abda34e15082c91d9dfb3fc0f298b">http://git.postgresql.org/pg/commitdiff/632ae6829f7abda34e15082c91d9dfb3fc0f298b</a>
+</p>
+
+<p>
+- Revise sinval code to remove no-longer-used tuple TID from inval
+  messages.  This requires adjusting the API for syscache callback
+  functions: they now get a hash value, not a TID, to identify the
+  target tuple.  Most of them weren't paying any attention to that
+  argument anyway, but plancache did require a small amount of fixing.
+  Also, improve performance a trifle by avoiding sending duplicate
+  inval messages when a heap_update isn't changing the catcache lookup
+  columns.
+  <a href="http://git.postgresql.org/pg/commitdiff/b5282aa893e565b7844f8237462cb843438cdd5e">http://git.postgresql.org/pg/commitdiff/b5282aa893e565b7844f8237462cb843438cdd5e</a>
+</p>
+
+<p>
+- Fix two issues in plpython's handling of composite results.  Dropped
+  columns within a composite type were not handled correctly.  Also,
+  we did not check for whether a composite result type had changed
+  since we cached the information about it.  Jan Urbański, per a bug
+  report from Jean-Baptiste Quenot
+  <a href="http://git.postgresql.org/pg/commitdiff/2dada0cc85ee36f4e2b32a0463cb75ad9466589a">http://git.postgresql.org/pg/commitdiff/2dada0cc85ee36f4e2b32a0463cb75ad9466589a</a>
+</p>
+
+<p>
+- Update 9.1 release notes to reflect commits through today.  Also do
+  another pass of copy-editing.
+  <a href="http://git.postgresql.org/pg/commitdiff/1a998474a7d88e8b340b179130b8368b734a3c30">http://git.postgresql.org/pg/commitdiff/1a998474a7d88e8b340b179130b8368b734a3c30</a>
+</p>
+
+<p>
+- Explain max_prepared_transactions requirement in isolation tests'
+  README.  Now that we have a test that requires nondefault settings
+  to pass, it seems like we'd better mention that detail in the
+  directions about how to run the tests.  Also do some very minor
+  copy-editing.
+  <a href="http://git.postgresql.org/pg/commitdiff/11c88e59a60b2096ab42fa7cf9bff542717ec1e0">http://git.postgresql.org/pg/commitdiff/11c88e59a60b2096ab42fa7cf9bff542717ec1e0</a>
+</p>
+
+<p>
+- Tag 9.1rc1.
+  <a href="http://git.postgresql.org/pg/commitdiff/d89b8daf5ee05f9c6fa63695e88d2315a224bf2d">http://git.postgresql.org/pg/commitdiff/d89b8daf5ee05f9c6fa63695e88d2315a224bf2d</a>
+</p>
+
+<p>
+- Fix performance problem when building a lossy tidbitmap.  As pointed
+  out by Sergey Koposov, repeated invocations of tbm_lossify can make
+  building a large tidbitmap into an O(N^2) operation.  To fix, make
+  sure we remove more than the minimum amount of information per call,
+  and add a fallback path to behave sanely if we're unable to fit the
+  bitmap within the requested amount of memory.  This has been wrong
+  since the tidbitmap code was written, so back-patch to all supported
+  branches.
+  <a href="http://git.postgresql.org/pg/commitdiff/08e1eedf247e04a9652d997a74ceb46d889124ba">http://git.postgresql.org/pg/commitdiff/08e1eedf247e04a9652d997a74ceb46d889124ba</a>
+</p>
+
+<p>
+Peter Eisentraut pushed:
+</p>
+
+<p>
+- Add "Reason code" prefix to internal SSI error messages.  This makes
+  it clearer that the error message is perhaps not supposed to be
+  understood by users, and it also makes it somewhat clearer that it
+  was not accidentally omitted from translation.  Idea from Heikki
+  Linnakangas, except that we don't mark "Reason code" for translation
+  at this point, because that would make the implementation too
+  cumbersome.
+  <a href="http://git.postgresql.org/pg/commitdiff/e5475a80d2fd1b99a7939a81a44b746821287a06">http://git.postgresql.org/pg/commitdiff/e5475a80d2fd1b99a7939a81a44b746821287a06</a>

+<p>
+- Adjust regression tests for error message change

+<p>
+- Use less cryptic variable names

+- Make pg_basebackup progress report translatable.  Also fix a
+  potential portability bug, because INT64_FORMAT is only guaranteed
+  to be available with snprintf, not fprintf.

+- Move \r out of translatable strings.  The translation tools are very

+</p>
+
+<p>
+- Improve detection of Python 3.2 installations.  Because of ABI
+  tagging, the library version number might no longer be exactly the
+  Python version number, so do extra lookups.  This affects
+  installations without a shared library, such as ActiveState's
+  installer.  Also update the way to detect the location of the
+  'config' directory, which can also be versioned.  Ashesh Vashi
+  <a href="http://git.postgresql.org/pg/commitdiff/f8c2029ef0bf83ceb2bb10ee28362305cfa9cdf2">http://git.postgresql.org/pg/commitdiff/f8c2029ef0bf83ceb2bb10ee28362305cfa9cdf2</a>
+</p>
+

+- Change PyInit_plpy to external linkage.  Module initialization

+  this change, the build with Python 3 fails on Windows.

+- Fix bogus comment that claimed that the new BACKUP METHOD line in
+  backup_label was new in 9.0.  Spotted by Fujii Masao.
+  <a href="http://git.postgresql.org/pg/commitdiff/2877c67bc24510c30bca477c876f5de427c85588">http://git.postgresql.org/pg/commitdiff/2877c67bc24510c30bca477c876f5de427c85588</a>

+- If backup-end record is not seen, and we reach end of recovery from
+  a streamed backup, throw an error and refuse to start up. The
+  restore has not finished correctly in that case and the data
+  directory is possibly corrupt.  We already errored out in case of
+  archive recovery, but could not during crash recovery because we
+  couldn't distinguish between the case that pg_start_backup() was
+  called and the database then crashed (must not error, data is OK),
+  and the case that we're restoring from a backup and not all the
+  needed WAL was replayed (data can be corrupt).  To distinguish those
+  cases, add a line to backup_label to indicate whether the backup was
+  taken with pg_start/stop_backup(), or by streaming (ie.
+  pg_basebackup).  This is a different implementation than what I
+  committed to 9.2 a week ago.  That implementation was not
+  back-patchable because it required re-initdb.  Fujii Masao

+- Strip whitespace from SQL blocks in the isolation test suite. This
+  is purely cosmetic, it removes a lot of IMHO ugly whitespace from

+- Add an SSI regression test that tests all interesting permutations
+  in the order of begin, prepare, and commit of three concurrent
+  transactions that have conflicts between them.  The test runs for a
+  quite long time, and the expected output file is huge, but this test
+  caught some serious bugs during development, so seems worthwhile to
+  keep. The test uses prepared transactions, so it fails if the server
+  has max_prepared_transactions=0. Because of that, it's marked as
+  "ignore" in the schedule file.  Dan Ports

+- Adjust total size in pg_basebackup progress report when reality

+  always be incorrect, since we don't know how much WAL is included.

+  patch increases the total size whenever we go past the estimate, to
+  make sure we never go above 100%.

+- Fix contrib/sepgsql and contrib/xml2 to always link required
+  libraries.  contrib/xml2 can get by without libxslt; the relevant
+  features just won't work.  But if doesn't have libxml2, or if
+  sepgsql doesn't have libselinux, the link succeeds but the module
+  then fails to work at load time.  To avoid that, link the require
+  libraries unconditionally, so that it will be clear at link-time
+  that there is a problem.  Per discussion with Tom Lane and KaiGai
+  Kohei.

+- Clean up 'chkselinuxenv' script.  Eliminate dependencies on "which",
+  as we don't really need that to be installed for proper testing.
+  Don't number the tests, as that increases the footprint of every
+  patch that wants to add or remove tests.  Make the test output more
+  informative, so that it's a bit easier to see what went right (or
+  wrong).  Spelling and grammar improvements.
