== Reviews ==

== Angewandte Patches ==

Heikki Linnakangas pushed:

- Support multiple concurrent pg_basebackup backups.  With this patch,
  pg_basebackup doesn't write a backup_label file in the data
  directory, so it doesn't interfere with a pg_start/stop_backup()
  based backup anymore. backup_label is still included in the backup,
  but it is injected directly into the tar stream.  Heikki
  Linnakangas, reviewed by Fujii Masao and Magnus Hagander.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=997b48ed96c476650f87ca75d65c9fc1f6273f5a

Bruce Momjian pushed:

- Move upgrade instructions into its own section under "Server Setup
  and Operation", merged from upgrade sections in "Installation from
  Source Code" and "Backup and Restore".  This now gives a single
  place for all upgrade information.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c5ba11f8fb1701441b96a755ea410b96bfe36170

- Update pg_upgrade docs to mention its use in a less risk-warning
  way, and update the pg_upgrade docs to mention its reliance on no
  changes to the storage format (the later based on Robert Haas's
  patch).
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=49450f01eca39308989cf668f60b7c345e72fc7b

  'postgres' database, not in the os-user database, per report from
  Magnus.

  and a mention of unencrypted passwords.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=00dd340210ed67900e03703eb088fdd5ab12c099

- Clarify documentation to state that "zero_damaged_pages" does not
  force data to disk, so the table or index should be recreated before
  the parameter is turned off again.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=7106f74e2a6feb31c022dd98e7d93ab656dc079d

- Document that CREATE VIEW that uses "*" for the column list will not
  auto-add columns later added to the base table.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5a6ba62be5364dbf973fd9b8631fd60acda03440

  with path variables, not directory paths.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=426227850be145b52cb610455000fc005df5ce4e

  Satoshi Nagayasu.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=df63aac678343cec522bc58588b70ab1374a6c93

- ALTER TABLE sometimes takes only ShareUpdateExclusiveLock.  Along
  the way, be more consistent about the wording we use here.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=7212c77d0cabcc468fec0b9cd7f2413b64b77050

- In docs, move PQrequestCancel() deprecation mention up to match
  other libpq doc mentions.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=b157a1d5554d6dfbd13fb605f08d51ce17532375

- Add doc comment that installation.sgml can't use xrefs.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8e6ae3d79c16ad8876c34f2cff8d667ca1cffb09

- Add C comment about why older compilers complain about
  basebackup.c's longjump.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=51dbc87dff5c32bfe627ec7b22c575c263de8251

- Rename macro DECIMAL to DECIMAL_T to help pgindent;  this is already
  done for a few other macros in that file, for other reasons.  I also
  remove pgindent/README mention of the file.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=97116ca4170b974d734cea364789c389b30e6ce1

- Adjust libpq docs to be clearer about 'hostaddr' usage by rewording
  and using an itemized list.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5ed45ac09c604555740e7365a722b641f3bce498

Andrew Dunstan pushed:

- Update docs on building for Windows to accomodate current reality.
  Document how to build 64 bit Windows binaries using the MinGW64 tool
  set.  Remove recommendation against using Mingw as a build platform.
  Be more specific about when Cygwin is useful and when it's not,  in
  particular note its usefulness for running psql, and add a note
  about building on Cygwin in non-C locales.  Per recent discussions.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=51be78b09a83b8d533e4a9f81cf9a7f2edde6654

- Set up PLPerl trigger data using C code instead of Perl code.  This
  is an efficiency change, and means we now no longer have to run "out
  $_TD; local $_TD = shift;", which was especially pointless in the
  case of non-trigger functions where the passed value was always
  undef anyway.  A tiny open issue is whether we should get rid of the
  $prolog argument of mkfunc, and the corresponding pushed value,
  which is now just a constant "false".  Tim Bunce, reviewed by Alex
  Hunsaker.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=ef19dc6d39dd2490ff61489da55d95d6941140bf

- Add  comment on why we're passing a useless 'false' to the plperl
  function compiler.  It's for compatibility with modules like
  PostgreSQL::PLPerl::NYTProf.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c73fe72e2735d20aa132640d8fab4e0eca1ced95

- Attempt to unbreak MSVC builds after pipe.c move.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=895ad83d702ed821f72ec7bdf1fba3db7da9d9d7

- Force strings passed to and from plperl to be in UTF8 encoding.
  String are converted to UTF8 on the way into perl and to the
  database encoding on the way back. This avoids a number of observed
  anomalies, and ensures Perl a consistent view of the world.  Some
  minor code cleanups are also accomplished.  Alex Hunsaker, reviewed
  by Andy Colson.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=50d89d422f9c68a52a6964e5468e8eb4f90b1d95

Simon Riggs pushed:

- Fix error code for canceling statement due to conflict with
  recovery.  All retryable conflict errors now have an error code that
  indicates that a retry is possible, correcting my incomplete fix of
  2010/05/12 Tatsuo Ishii and Simon Riggs, input from Robert Haas and
  Florian Pflug
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8585ad36254199ca63700707ee78890da1755e4d

- Create new errcode for recovery conflict caused by db drop on
  master.  Previously reported as ERRCODE_ADMIN_SHUTDOWN, this case is
  now reported as ERRCODE_T_R_DATABASE_DROPPED. No message text
  change.  Unlikely to happen on most servers, so low impact change to
  allow session poolers to correctly handle this situation.  Tatsuo
  Ishii, edits by me, review by Robert Haas.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9e95c9ad558bafa26efbab50f77929de4ade5f90

- Re-classify ERRCODE_DATABASE_DROPPED to 57P04
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=56b21b7ae38bc1efb701e7ebfd208e2e194e7998

Tom Lane pushed:

- Prevent buffer overrun while parsing an integer in a "query_int"
  value.  contrib/intarray's gettoken() uses a fixed-size buffer to
  collect an integer's digits, and did not guard against overrunning
  the buffer.  This is at least a backend crash risk, and in principle
  might allow arbitrary code execution.  The code didn't check for
  overflow of the integer value either, which while not presenting a
  crash risk was still bad.  Thanks to Apple Inc's security team for
  reporting this issue and supplying the fix.  Security: CVE-2010-4015
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=7ccb6dc2d3e266a551827bb99179708580f72431

- Update release notes.  Security: CVE-2010-4015
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=43054624979de3205fbc432f15defd4b9d5922e9

- Support LIKE and ILIKE index searches via contrib/pg_trgm indexes.
  Unlike Btree-based LIKE optimization, this works for
  non-left-anchored search patterns.  The effectiveness of the search
  depends on how many trigrams can be extracted from the pattern.
  (The worst case, with no trigrams, degrades to a full-table scan, so
  this isn't a panacea.  But it can be very useful.) Alexander
  Korotkov, reviewed by Jan Urbanski.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=6e2f3ae8842392c46ccc91a9ce4bba92296890cb

- Clean up missed change to plpython expected files.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=907855ac759a221f95b502cd7cbf2ec851fe9523

- Repair multiple breakage in Windows-specific code for appending '.exe'.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=cd7d748d51df3c5dedcc49a3603e6fa9c050f237

ITAGAKI Takahiro pushed:

- Add a link from client_encoding parameter to the list of character
  sets in documentation.  Thom Brown
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=03282bfa8973f3a77ca3e7c14847a5a11d07d6a2

- Fix wrong error reports in 'number of array dimensions exceeds the
  maximum allowed' messages, that have reported one-less dimensions.
  Alexey Klyukin
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=0c707aa4583a5584f4c3f4ad1697bb206ed0d65a

Magnus Hagander pushed:

- Undefine setlocale() macro on Win32.  New versions of libintl
  redefine setlocale() to a macro which causes problems when the
  backend and libintl are linked against different versions of the
  runtime, which is often the case in msvc builds.  Hiroshi Inoue,
  slightly updated comment by me
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5273f2143416f6340f6ee876facfa6f7a87453a0

- Fix typo.  Thom Brown
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f001cb38b67b0f2f5f4cfd1e32f86866da8c8693

- Include more status information in walsender results.  Add the
  current xlog insert location to the response of IDENTIFY_SYSTEM, and
  adds result sets containing start and stop location of backups to
  BASE_BACKUP responses.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=76129e7f14b4605db0a046e13abef0e255ffe007

- Use single quotes when there are backslashes in the filename.  In
  the hope of unbreaking the buildfarm
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=39fbec73b0dd15df8955baad57685082ec0cef8f

- Attempt to un-break the documentation build again Another case of
  <xref linkend> in the documentation that builds INSTALL, which is
  not allowed.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=afb6dee1e3b93af05e35873c19c068e8ac7eb74b

- IDENTIFY_SYSTEM now returns 3 fields, not 2
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=cedd6515ba68f46dd7e75a65d4c98330ced0ba7a

Peter Eisentraut pushed:

- Add validator to PL/Python.  Jan Urbański, reviewed by Hitoshi
  Harada
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=15f55cc38a82dfa3d7898a7c30a303b1b3e87dc3

- Wrap PL/Python SPI calls into subtransactions.  This allows the
  language-specific try/catch construct to catch and handle exceptions
  arising from SPI calls, matching the behavior of other PLs.  As an
  additional bonus you no longer get all the ugly "unrecognized error
  in PLy_spi_execute_query" errors.  Jan Urbański, reviewed by Steve
  Singer
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=0c5933d0104c1788479592a84cca53da357381f9

Robert Haas pushed:

- Log restartpoints in the same fashion as checkpoints.  Prior to 9.0,
  restartpoints never created, deleted, or recycled WAL files, but now
  they can.  This code makes log_checkpoints treat checkpoints and
  restartpoints symmetrically.  It also adjusts up the documentation
  of the parameter to mention restartpoints.  Fujii Masao.  Docs by
  me, as suggested by Itagaki Takahiro.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=0af695fd43b6889613a4035e3cdfcc0fc1b7936a

- Various sepgsql corrections.  KaiGai Kohei
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c7689ee73346d198177dee538501bb1148c8cebb

- Minor sepgsql regression test fixes.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=87d967f70f4866c17404f6a9b8062f892ed31e08

- sepgsql doc fix.  KaiGai Kohei
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=4ff9dec1386b714f6c26a52ca6880b14e94dd1db

- Further sepgsql documentation cleanup.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=4c4daf671074cc64290e9255c14365b55bf7a47b

- Avoid maintaining three separate copies of the error codes list.
  src/pl/plpgsql/src/plerrcodes.h, src/include/utils/errcodes.h, and a
  big chunk of errcodes.sgml are now automatically generated from a
  single file, src/backend/utils/errcodes.txt.  Jan Urbański, reviewed
  by Tom Lane.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=ddfe26f6441c24660595c5efe5fd0bd3974cdc5c

- Preserve copyright notice from old errcodes.h file.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=b8a0467e10a41d32ecf889d40de81223e0439c5b

- Unbreak the VPATH build.  My commit
  ddfe26f6441c24660595c5efe5fd0bd3974cdc5c of 2010-02-03 broke it.
  Per buildfarm.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=dde9684d65ed66656f765d3fd97f2e522a189132

- Unbreak 'configure' followed immediately by 'make install'.  More
  fallout from ddfe26f6441c24660595c5efe5fd0bd3974cdc5c.  Report by
  Fujii Masao.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=b87811ee273360c45d92b0e7bb7e67670312c221

- Make handling of errcodes.h more consistent with other generated
  headers.  This fixes make distprep, and seems more robust in other
  ways as well.  Some special handling is required because
  errcodes.txt is needed by some stuff in src/port, but just by
  src/backend as is the case for the other generated headers.  While
  I'm at it, fix a few other things that were overlooked in the
  original patch.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=356f2cbbb42811596820c94aaec2e32ad1ec58d8

- Use $(MAKE) rather than make.  Per buildfarm.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=6f59a5e5dd73ec2c448dd7038accf5aaba6dc04b

- Update ALTER TABLE docs to mention using VACUUM FULL for rewrites.
  Remove the claim that ALTER TABLE .. SET DATA TYPE is the fastest
  way of rewriting a table, since it no longer is.  Noah Misch and
  Robert Haas, based on a suggestion from Tom Lane.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=edad08ba545b43261b4d54d65122b45c9b5ee801

- Avoid including postgres.h in frontend compiles of src/port.  This
  isn't kosher, and doesn't play nicely with my recent changes to the
  Makefile in this directory.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8201aea90c2b171808c65836fcce4f29b22a9dbb

- Move pipe.c into the backend.  It's full of backend-specific error
  reporting, so it's neither possible nor necessary for this to be
  used from frontend code.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=b1e65c32168a2b64276a57be8c4dc5a63d33e12d

- Clarify comment in ATRewriteTable().  Make sure it's clear that the
  prohibition on adding a column with a default when the rowtype is
  used elsewhere is intentional, and be a bit more explicit about the
  other cases where we perform this check.
  http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9e7e1172a53054dc14574e42865ea8213bc06371

- Tighten ALTER FOREIGN TABLE .. SET DATA TYPE checks.  If the foreign
  table's rowtype is being used as the type of a column in another
  table, we can't just up and change its data type.  This was already
  checked for composite types and ordinary tables, but we previously
  failed to enforce it for foreign tables.
