== Applied Patches ==

Magnus Hagander pushed:

- Exclude sepgsql from MSVC regression testing as well. In passing,
  change exclusion in the build to follow the same pattern as other
  always-excluded modules.;a=commitdiff;h=97520809424d46c55e2faf73b5f09cb64b52f4a5

- Typo fix for MemSet size.  Fujii Masao.;a=commitdiff;h=966d4f52c258aba8187d61fdc1e10b80d560f07c

- Use GSSAPI library for SSPI auth, when native SSPI is not available.
  This allows non-Windows clients to connect to a Windows server with
  SSPI authentication.  Christian Ullrich, largely modified by me;a=commitdiff;h=4ea1a273fbc20b29ba4aacd3c21030bd62296d7d

- Add option to include WAL in base backup.  When included, this makes
  the base backup a complete working "clone" of the initial database,
  ready to have a postmaster started against it without the need to
  set up any log archiving or similar.  Magnus Hagander, reviewed by
  Fujii Masao and Heikki Linnakangas;a=commitdiff;h=507069de6dbe18c2163f27fbc780673eef8c5622

Heikki Linnakangas pushed:

- Fix typo in the psql \d query handling, so that we use the correct
  query against 9.0 servers.;a=commitdiff;h=74be35b07cf09350168018234026df94184f8991

- Update psql's \copyright to match the text we have in the COPYRIGHT

Robert Haas pushed:

- More documentation cleanup for sepgsql.  Thom Brown and Robert Haas.;a=commitdiff;h=ea2c2641f908cde198a9999100d847078a05385b

- Fix thinko in ALTER FOREIGN TABLE documentation.  Noah Misch.;a=commitdiff;h=558d1c95ae6afb8728f70a150c593f7e7aa5fac1

- Correct ALTER TYPE -> SET DATA TYPE in ALTER TABLE documentation.
  The latter is the correct name of the operation to change the data
  type of a column.  Noah Misch.;a=commitdiff;h=2b2b2ae2aa4a7089aee729e67bb323154da3841a

- Remove arbitrary ALTER TABLE .. ADD COLUMN restriction.  The
  previous coding prevented ALTER TABLE .. ADD COLUMN from being used
  with a non-NULL default in situations where the table's rowtype was
  being used elsewhere.  But this is a completely arbitrary
  restriction since you could do the same operation in multiple steps
  (add the column, add the default, update the table).  Inspired by a
  patch from Noah Misch, though I didn't use his code.;a=commitdiff;h=a06e41deebdf74b8b5109329dc75b2e9d9057962

- Add a comment explaining why we force physical removal of OIDs.
  Noah Misch, slightly revised.;a=commitdiff;h=5c2a7c6e97741564ab4ff336eac8d8227485dd4c

- Restore ALTER TABLE .. ADD COLUMN w/DEFAULT restriction.  This
  reverts commit a06e41deebdf74b8b5109329dc75b2e9d9057962 of
  2011-01-26.  Per discussion, this behavior is not wanted, as it
  would need to change if we ever made composite types support

- Try to avoid running with a full fsync request queue.  When we need
  to insert a new entry and the queue is full, compact the entire
  queue in the hopes of making room for the new entry.  Doing this on
  every insertion might worsen contention on BgWriterCommLock, but
  when the queue it's full, it's far better than allowing the backend
  to perform its own fsync, per testing by Greg Smith as reported in
  Original idea from Greg Smith.  Patch by me.  Review by Chris Browne
  and Greg Smith;a=commitdiff;h=7f242d880b5b5d9642675517466d31373961cf98

Peter Eisentraut pushed:

- Refactor PLy_spi_prepare to save two levels of indentation.  Instead
  of checking whether the arglist is NULL and then if its length is 0,
  do it in one step, and outside of the try/catch block.  Jan Urbański;a=commitdiff;h=52713d02c73926898629e349a9804cd0cae0470b

- Call PLy_spi_execute_fetch_result inside the try/catch block.  This
  way errors from fetching tuples are correctly reported as errors in
  the SPI call.  While at it, avoid palloc(0).  Jan Urbański;a=commitdiff;h=88dcdf9007895b6703dfaf90d15244055384c603

- Document the "S" option for psql's \dn command in the psql help.
  This option was recently introduced, but the documentation in help.c
  was not updated.;a=commitdiff;h=77ff840835bc40693f36281ab394de881cb327eb

- Fix compiler warnings.  Older versions of GCC appear to report these
  with the current standard option set, newer versions need

- autoreconf.  Synchronize with (someone
  must have forgotten to run autoheader or autoreconf), and clean up
  some spurious change in configure introduced by the last commit

- Improve exception usage in PL/Python.  Use the built-in TypeError,
  not SPIError, for errors having to do with argument counts or types.
  Use SPIError, not simply plpy.Error, for errors in
  PLy_spi_execute_plan.  Finally, do not set a Python exception if
  PyArg_ParseTuple failed, as it already sets the correct exception.
  Jan Urbański;a=commitdiff;h=582b5ac62e74a553e72151b321804a7b2e5fed6f

- Do not prefix error messages with the string "PL/Python: " It is
  redundant, given the error context.  Jan Urbański;a=commitdiff;h=5829738868f8d87263b6d31675e08147d8d7c188

- Use -Wformat-security when available.;a=commitdiff;h=8b6f5f25102f9e2503ce18af77b6fd547a2192ca

- Also save the error detail in SPIError. The temporarily broken
  plpython_unicode test shows a case where this is used.  Do remaining
  fix-ups on the expected files at the same time.;a=commitdiff;h=418df3a5dd94d9f02b895f9c161b2435d61e0729

- Translation updates for release 9.0.3, 8.4.7, 8.3.14, 8.2.20.;a=commitdiff;h=7f2d75408b63fab9cc613b3d60d057f6d3ec3adc;a=commitdiff;h=bdf3a806466b18d89bd92b93bd83bc762450d9e1;a=commitdiff;h=e7a1793f55f479e360725a1300d0444a4282d14b;a=commitdiff;h=d5a0bb5acc87ad272508ce0f1d83f581cb634d27

Bruce Momjian pushed:

- In test_open_sync(), writes kilobytes as intended, not by bytes.;a=commitdiff;h=9fc01922831aba350a61844882c229026ca8bf0b

- Use XLOG_BLCKSZ in pg_test_fsync, rather than our own define, but
  verify it is 8k as expected.;a=commitdiff;h=9dd7933937a076ce7573944b8d1d42e618163440

- Use consistent spacing for PGAPPICON Makefile option.;a=commitdiff;h=d7a714828f1a4d09adef68b58674a6266aa8fa03

- Update warning about synchronous-commit durability, per suggestion
  from Robert Haas.;a=commitdiff;h=a91c950658016162020258574fb98aba182a5eac

- Adjust pg_test_fsync to always do XLOG_BLCKSZ-sized writes, rather
  than always 8k writes, per suggestion from Tom Lane.  Also adjust
  open_sync output layout.;a=commitdiff;h=64bc872761bc9bf730307957f09f44a3eabbe3af

- Update sync commit performance documentation to be consistent with
  other non-durable items, per Robert Haas.;a=commitdiff;h=e84730a916bce0635eb78205d2ea4746ee664d68

- Update contrib documention mentions to point to actual documentation
  sections, rather than just calling it "/contrib/module_name".  Also
  update pg_test_fsync build instructions now that it is in /contrib.;a=commitdiff;h=159e3d86292cfec2a2828f9f69ac7a6cb1be242d

- In pg_test_fsync, use K(1024) rather than k(1000) for write size

- Per Peter Eisentraut, use 'kB' for kilobyte, not 'K'.;a=commitdiff;h=4fec63f94e8edb6181eb3e1e25e979062ab17450

- Restructure streaming docs so streaming seems more integrated in the
  paragraphs, per suggestion from Dan Birken.;a=commitdiff;h=81c48aeaa8fd34f90ab6d6f1d56564d34ac4aa59

- Update non-durable docs about non-synchronous-commit allowing
  transaction loss for a _database_ crash.;a=commitdiff;h=b34ee30115fb6b8da8c3024705bd4ba0339212c1

- Properly capitalize documentation headings;  some only had
  initial-word capitalization.;a=commitdiff;h=5d5678d7c3b336a5aacf15d66ac3ebccaab929f2

Tom Lane pushed:

- Replace pg_class.relhasexclusion with pg_index.indisexclusion.
  There isn't any need to track this state on a table-wide basis, and
  trying to do so introduces undesirable semantic fuzziness.  Move the
  flag to pg_index, where it clearly describes just a single index and
  can be immutable after index creation.;a=commitdiff;h=bd1ad1b019cda851a3e925133c056930368e6424

- Remove old claim that ExclusiveLock is sometimes taken on system
  catalogs.  We used to do that on pg_listener, but pg_listener is no
  more.  Also add a bit more documentation for ShareRowExclusive mode.;a=commitdiff;h=5042d16d1210d1a10a896a0fcf81230ff4b0e383

- Change inv_truncate() to not repeat its systable_getnext_ordered()
  scan.  In the case where the initial call of
  systable_getnext_ordered() returned NULL, this function would
  nonetheless call it again.  That's undefined behavior that only by
  chance failed to not give visibly incorrect results.  Put an if-test
  around the final loop to prevent that, and in passing improve some
  comments.  No back-patch since there's no actual failure.  Per
  report from YAMAMOTO Takashi.;a=commitdiff;h=7ab6f2da23516e48174f3f144ee9ef19bdc287fb

- Improve grammar and spelling in durability discussion.;a=commitdiff;h=85f345bec2d7f2ccb67b98b06342c86372ecf3b1

- Update release notes for releases 9.0.3, 8.4.7, 8.3.14, and 8.2.20.;a=commitdiff;h=29d442199ac978b2272d1d96648585943f499fe6

- Don't include <asm/ia64regs.h> unnecessarily.  We only need that
  header when compiling with icc, since the gcc variant of
  ia64_get_bsp() uses in-line assembly code.  Per report from Frank
  Brendel, the header doesn't exist on all IA64 platforms; so don't
  include it unless we need it.;a=commitdiff;h=0ac8c8df85951a6c4815f5e8e0491b6bba4534b7

- Update release notes.  Security: CVE-2010-4015;a=commitdiff;h=aefb8d9198926e9f7717d6420b802ae4b6352293

- Rephrase pg_conversion description to avoid splitting link across
  page.  The link to the CREATE CONVERSION manual page was split
  across a page boundary in the PDF output, leading to "\pdfendlink
  ended up in different nesting level than \pdfstartlink" error while
  building PDFs.  It wouldn't be worth changing text that's undergoing
  active editing to avoid this, since other editing might result in
  moving the link away from the page end anyway.  But this paragraph
  has been static for a long time, so might as well fix it to prevent
  it from being an issue in future.;a=commitdiff;h=20a0f97273e765598420b261685764b40810c812

- Copy-edit a paragraph in the contrib/seg documentation.  Although
  this improves the style, an ulterior motive is to keep the two table
  links from breaking across lines in PDF output, per complaint from
  Josh Kupershmidt.;a=commitdiff;h=b2826ad52d72195317a13c2074a5cd002c98a338

- Make installation.sgml build standalone again.  We must not try to
  link to sections that aren't part of the standalone "make INSTALL"
  build.  Corrects build failure introduced in commit

- Make reduce_outer_joins() smarter about semijoins.
  reduce_outer_joins() mistakenly treated a semijoin like a left join
  for purposes of deciding whether not-null constraints created by the
  join's quals could be passed down into the join's left-hand side
  (possibly resulting in outer-join simplification there).  Actually,
  semijoin works like inner join for this purpose, ie, we do not need
  to see any rows that can't possibly satisfy the quals.  Hence,
  two-line fix to treat semi and inner joins alike.  Per observation
  by Andres Freund about a performance gripe from Yazan Suleiman.
  Back-patch to 8.4, since this oversight has been there since the
  current handling of semijoins was implemented.;a=commitdiff;h=9688c4e6f1516d2fc0db5d200112c4d91538878d

ITAGAKI Takahiro pushed:

- Make 'on' uppercase in a sql example.;a=commitdiff;h=69039ea8b5569caf09b211f46fa9064468fee3b3

Marc Fournier pushed:

- Tag 9.0.3. 8.4.7, 8.3.14, 8.2.20.;a=commitdiff;h=2fb64d857003c91378ba86b03d753a63ebee95b2;a=commitdiff;h=7df910c7d128b775220d529e23813bb4663dba4e;a=commitdiff;h=5370e1a0014e17f0a3c8f65601c3145c824d9b3f;a=commitdiff;h=f62f223b8e7519d741203d71f5bd8fc7693c0b41

Andrew Dunstan pushed:

- Enable building with the Mingw64 compiler.  This can be used to
  build 64 bit Windows binaries, not only on 64 bit Windows but on
  supported cross-compiling hosts including 32 bit Windows, Cygwin,
  Darwin and Linux.;a=commitdiff;h=91812df4ed0facfb90bec3f9430dd5a97d56f695

- Fix typo;a=commitdiff;h=48c9de80283d4bbdf9bec2f2f929b23f1676f8f9
