This is intended as infrastructure to support integration with label-based mandatory access control systems such as SE-Linux. Further changes (mostly hooks) will be needed, but this is a big chunk of it. KaiGai Kohei and Robert Haas. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=4d355a8336e0f2265b31d678ffd1ee5cf9e79fae - Fix duplicate OIDs introduced by SECURITY LABEL patch. Report by Shigeru Hanada. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=eacb22ec476a7bc49bdb2054a76a2b27a429a295 - Adjust pg_archivecleanup docs to match message changes made 2010-06-17. Erik Rijkers. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=1f0eb5de9eb56a2eb71cc538f12861b084e7b03b ITAGAKI Takahiro pushed: - Add DISCARD to the command_no_begin list for AUTOCOMMIT=off. Backpatch to 8.3. Reported by Sergey Burladyan. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=d08c698d9d47f9d004fd0bb6212ca80259e2fe9c - Only DISCARD ALL should be in the command_no_begin list. We allowes DISCARD PLANS and TEMP in a transaction. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=62b6aaa40b2abb26edf18d1cd00dffcac090f67a Andrew Dunstan pushed: - Fix MSVC builds for dummy_seclabel breakage. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f00847dc012e9c5219ef0e8e212d173d24700275 Alvaro Herrera pushed: - In doc/src/sgml/ref/security_label.sgml, add missing agg_type nonterminal description in new reference page. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=3bb27fb503b421dae5c5d95d75842bbc048f2fab Bruce Momjian pushed: - Add mention of installing pg_upgrade_support in pg_upgrade doc section title, per suggestion from Ian Barwick. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9c5f4f6cb50dd22028acc0b6f20291a5edcac62b - Mention in pg_upgrade docs that the proper Win32 service name should be used. Per report from Harald Armin Massa. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=6b44b9ba56e02d63425a8d950ef141bb007745ff - Mention that pg_upgrade requires write permission in the current directory. Per report from Harald Armin Massa. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=ae9acb677950cf2afa037349b73fa3351d6e1d31 - Properly close files after read file failure to prevent potential resource leak. Of course, any such failure aborts pg_upgrade, but might as well be clean about it. Per patch from Grzegorz Jaskiewicz. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f175884520949fbc52908d2f4b2baacde5906ebc - Fix leak patch that was using fclose() instead of close(). http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=a1bb570de97c71eba3c1b7a067063e8ba28c41d5 - In pg_upgrade, properly handle oids > 2^31 by using strtoul() internally rather than atol(). Per report from Brian Hirt http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9340fb80b1dba5528c0d16b24985369659a19377 - Use macro atooid() for conversion of strings to oids, per suggestion from Tom. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=807005c024aa57b5af729d021263cbf179fd5121 - Have pg_upgrade use strtoul(), not strtol(). http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=fe61db6f0ceb508357bcddc39b388e2806cf11d0 Tom Lane pushed: - Fix PlaceHolderVar mechanism's interaction with outer joins. The point of a PlaceHolderVar is to allow a non-strict expression to be evaluated below an outer join, after which its value bubbles up like a Var and can be forced to NULL when the outer join's semantics require that. However, there was a serious design oversight in that, namely that we didn't ensure that there was actually a correct place in the plan tree to evaluate the placeholder :-(. It may be necessary to delay evaluation of an outer join to ensure that a placeholder that should be evaluated below the join can be evaluated there. Per recent bug report from Kirill Simonov. Back-patch to 8.4 where the PlaceHolderVar mechanism was introduced. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=eb229505103eb5494c33832d422584bfdee03fc6 - Fix another small oversight in command_no_begin patch. Need a "return false" to prevent tests from continuing after we've moved the "query" pointer. As it stood, it'd accept "DROP DISCARD ALL" as a match. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=112c3fc6db62b39ded8965eddce1f4213308b957 - Fix incorrect usage of non-strict OR joinclauses in appendrel indexscans. By chance I happened to notice that bug #5076 was still broken in the 8.3 branch, though it worked everywhere else. The reason is that 8.3's version of adjust_appendrel_attrs_mutator neglected to adjust RestrictInfo.nullable_relids. This was an oversight in my patch of 2009-04-16, which I apparently corrected in the later branches on 2009-08-13 without realizing that it affected the 8.3 branch as well. By the time the bug report was filed, it was not reproducible in 8.4. I don't recall if I wrote it off as already fixed, or it just fell through the cracks; but anyway it's been a live bug in 8.3 for a year. - Improve messages for too many private files/dirs. Per Alexey Parshin. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=5ac144d5c2906cc4b45423ac6575653a8df1b3d0 - Update release notes for releases 9.0.1, 8.4.5, 8.3.12, 8.2.18, 8.1.22, 8.0.26, and 7.4.30. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=a5683ea0423752cca323e528cb160273ad794054 - Fix back-branch breakage from ill-advised last-minute commit. - Throw an appropriate error if ALTER COLUMN TYPE finds a dependent trigger. Actually making this case work, if the column is used in the trigger's WHEN condition, will take some new code that probably isn't appropriate to back-patch. For now, just throw a FEATURE_NOT_SUPPORTED error rather than allowing control to reach the "unexpected object" case. Per bug #5688 from Daniel Grace. Back-patch to 9.0 where the possibility of such a dependency was introduced. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=1f0b62e8c28026f5d1d3693087f7b4aef6a191af - Remove excess argument to open(2). Many compilers don't complain about this, but some do, and it's certainly wrong. Back-patch to 8.4 where the error was introduced. Mark Kirkwood. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=e77f605d431c488983d6c96cb3513c691bf1907c - Behave correctly if INSERT ... VALUES is decorated with additional clauses. In versions 8.2 and up, the grammar allows attaching ORDER BY, LIMIT, FOR UPDATE, or WITH to VALUES, and hence to INSERT ... VALUES. But the special-case code for VALUES in transformInsertStmt() wasn't expecting any of those, and just ignored them, leading to unexpected results. Rather than complicate the special-case path, just ensure that the presence of any of those clauses makes us treat the query as if it had a general SELECT. Per report from Hitoshi Harada. http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=3a13f12b3a18da0a61571cb134fdecea03a10d6f Peter Eisentraut pushed: - Update ecpglib error code listing. Satoshi Nagayasu http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=fe48d9471eea6a5e8f8162bfed7d8f7c264904ab - Add/fix caching on some configure checks http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=804a786c958d44fdf3b2e2d4774618f919759dc8 - Translation updates for 9.0.1, 8.4.5, 8.3.12, 8.2.18, 8.1.22, 8.0.26, and 7.4.30. Marc Fournier pushed: - Tag 9.0.1, 8.4.5, 8.3.12, 8.2.18, 8.1.22, 8.0.26, and 7.4.30. == Rejected Patches (for now) == No one was disappointed this week :-) == Pending Patches == Tom Lane sent in a patch to fix a bug in subquery JOIN ordering.

Fujii Masao sent in another revision of the patch to change libpq for synchronous replication. Andrew Dunstan sent in another revision of the patch to extend ENUMs. Robert Haas sent in another revision of the patch to implement merge-append. Gurjeet Singh sent in a patch to allow people to replace a primary key with another index. Pavel Stehule sent in three revisions of a patch to add FOR...IN [array] to PL/pgsql. Pavel Stehule sent in a patch to implement a subscripts function. Gregory Stark sent in a patch to add gtrusage profiling to EXPLAIN output.
