<p><strong>Correctifs appliqu&eacute;s</strong></p>
<p>Heikki Linnakangas a pouss&eacute;&nbsp;:</p>
<ul>
<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=997b48ed96c476650f87ca75d65c9fc1f6273f5a">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=997b48ed96c476650f87ca75d65c9fc1f6273f5a</a></li>
<li>Fix typo. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=32866837f005fcfdd1e1289f08a89a7c519da000">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=32866837f005fcfdd1e1289f08a89a7c519da000</a></li>
<li>Remove spurious word, spotted by Thom Brown. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=44df84df72b5eb43384bc7288713c2f80db7273d">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=44df84df72b5eb43384bc7288713c2f80db7273d</a></li>
</ul>
<p>Bruce Momjian a pouss&eacute;&nbsp;:</p>
<ul>
<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c5ba11f8fb1701441b96a755ea410b96bfe36170">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c5ba11f8fb1701441b96a755ea410b96bfe36170</a></li>
<li>Fix SGML markup for upgrade doc addition. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=ff20fbd6c21929cd5c78f154c8364ce746de9c03">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=ff20fbd6c21929cd5c78f154c8364ce746de9c03</a></li>
<li>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). 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=49450f01eca39308989cf668f60b7c345e72fc7b">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=49450f01eca39308989cf668f60b7c345e72fc7b</a></li>
<li>Fix pg_upgrade to create pg_authid restore functions in the 'postgres' database, not in the os-user database, per report from Magnus. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=6238473adb119a5a11061e40e159e8c5187fe492">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=6238473adb119a5a11061e40e159e8c5187fe492</a></li>
<li>In pg_authid.rolpassword docs, make "md5" appear as a literal. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=2dbed56c5a86d45a66f41e6a8a16295bbfe46646">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=2dbed56c5a86d45a66f41e6a8a16295bbfe46646</a></li>
<li>Improve docs for pg_authid encryption description with better markup and a mention of unencrypted passwords. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=00dd340210ed67900e03703eb088fdd5ab12c099">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=00dd340210ed67900e03703eb088fdd5ab12c099</a></li>
<li>Add pg_upgrade comment for why we can't use template1 inheritance for the support functions. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=2bb87a61a84ab74b7ba820aac787443a78897bf4">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=2bb87a61a84ab74b7ba820aac787443a78897bf4</a></li>

<li>Clarify pg_upgrade install instructions, per suggestion from Robert Haas. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=902aae5ec58f71b8d9f7efb5ed474d0f5439439d">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=902aae5ec58f71b8d9f7efb5ed474d0f5439439d</a></li>
<li>Document that Slony can do upgrades easier _because_ it supports replication between different Postgres major versions. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=e8cdc238cfa3fda4185fe6a9826dbdf0a107f789">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=e8cdc238cfa3fda4185fe6a9826dbdf0a107f789</a></li>

<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=6c6e6f7fd3ffa984a202b910ef3237e26f9d3c2e">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=6c6e6f7fd3ffa984a202b910ef3237e26f9d3c2e</a></li>
<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=7106f74e2a6feb31c022dd98e7d93ab656dc079d">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=7106f74e2a6feb31c022dd98e7d93ab656dc079d</a></li>

<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5a6ba62be5364dbf973fd9b8631fd60acda03440">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5a6ba62be5364dbf973fd9b8631fd60acda03440</a></li>

<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=2b6e2dee7805ec5b477af00c01c54c208bf106eb">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=2b6e2dee7805ec5b477af00c01c54c208bf106eb</a></li>
<li>Mark all GUC variables with &lt;varname&gt; markup, rather than &lt;literal&gt;. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=03c25dd900d97c0868ad20b925a78d41ec603578">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=03c25dd900d97c0868ad20b925a78d41ec603578</a></li>
<li>Clearify macro IS_PATH_VAR_SEP in path.c so it is clear this is a path variable, not a directory path. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=bffb638d16999ee7d3c8796e77dd87ac82719c7d">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=bffb638d16999ee7d3c8796e77dd87ac82719c7d</a></li>
<li>Rename function to first_path_var_separator() to clarify it works with path variables, not directory paths. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=426227850be145b52cb610455000fc005df5ce4e">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=426227850be145b52cb610455000fc005df5ce4e</a></li>

<li>In docs, PL is Procedural Language, not Programming Language. Satoshi Nagayasu. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=df63aac678343cec522bc58588b70ab1374a6c93">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=df63aac678343cec522bc58588b70ab1374a6c93</a></li>
<li>ALTER TABLE sometimes takes only ShareUpdateExclusiveLock. Along the way, be more consistent about the wording we use here. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=7212c77d0cabcc468fec0b9cd7f2413b64b77050">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=7212c77d0cabcc468fec0b9cd7f2413b64b77050</a></li>

<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8e6ae3d79c16ad8876c34f2cff8d667ca1cffb09">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8e6ae3d79c16ad8876c34f2cff8d667ca1cffb09</a></li>

<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=97116ca4170b974d734cea364789c389b30e6ce1">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=97116ca4170b974d734cea364789c389b30e6ce1</a></li>
<li>Adjust libpq docs to be clearer about 'hostaddr' usage by rewording and using an itemized list. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5ed45ac09c604555740e7365a722b641f3bce498">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5ed45ac09c604555740e7365a722b641f3bce498</a></li>
</ul>
<p>Andrew Dunstan a pouss&eacute;&nbsp;:</p>
<ul>
<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=51be78b09a83b8d533e4a9f81cf9a7f2edde6654">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=51be78b09a83b8d533e4a9f81cf9a7f2edde6654</a></li>
<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=ef19dc6d39dd2490ff61489da55d95d6941140bf">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=ef19dc6d39dd2490ff61489da55d95d6941140bf</a></li>
<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c73fe72e2735d20aa132640d8fab4e0eca1ced95">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c73fe72e2735d20aa132640d8fab4e0eca1ced95</a></li>
<li>Attempt to unbreak MSVC builds after pipe.c move. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=895ad83d702ed821f72ec7bdf1fba3db7da9d9d7">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=895ad83d702ed821f72ec7bdf1fba3db7da9d9d7</a></li>
<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=50d89d422f9c68a52a6964e5468e8eb4f90b1d95">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=50d89d422f9c68a52a6964e5468e8eb4f90b1d95</a></li>

<p>Simon Riggs a pouss&eacute;&nbsp;:</p>
<ul>
<li>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 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8585ad36254199ca63700707ee78890da1755e4d">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8585ad36254199ca63700707ee78890da1755e4d</a></li>
<li>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.

<li>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

<li>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.

<li>Log restartpoints in the same fashion as checkpoints. Prior to 9.0, restartpoints never created, deleted, or recycled WAL files, but now they can.

<li>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 Urba&#324;ski, reviewed by Tom Lane.

<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=356f2cbbb42811596820c94aaec2e32ad1ec58d8">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=356f2cbbb42811596820c94aaec2e32ad1ec58d8</a></li>

<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=edad08ba545b43261b4d54d65122b45c9b5ee801">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=edad08ba545b43261b4d54d65122b45c9b5ee801</a></li>
<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8201aea90c2b171808c65836fcce4f29b22a9dbb">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=8201aea90c2b171808c65836fcce4f29b22a9dbb</a></li>
<li>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.

<li>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. 
<a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9e7e1172a53054dc14574e42865ea8213bc06371">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9e7e1172a53054dc14574e42865ea8213bc06371</a></li>
<li>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.
