Fujii Masao, with additional hacking by me. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/240067b3b0ff989d2b28f4f917f7958f2ec76b05">http://git.postgresql.org/pg/commitdiff/240067b3b0ff989d2b28f4f917f7958f2ec76b05</a></li> <li>Add casts from int4 and int8 to numeric.

When we release and reacquire SerializableXactHashLock, we must recheck whether an R/W conflict still needs to be flagged, because it could have changed under us in the meantime. And when we release the partition lock, we must re-walk the list of predicate locks from the beginning, because our pointer could get invalidated under us. Bug report #5952 by Yamamoto Takashi. Patch by Kevin Grittner. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/632f0faa7c975e8984ce0f1d6b631478e41a96c2">http://git.postgresql.org/pg/commitdiff/632f0faa7c975e8984ce0f1d6b631478e41a96c2</a></li> <li>Fix some sloppiness in new PL/python get_source_line() function. Jan Urba&#324;ski <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/b6bc481d5540a3ad0d39db1e9881e6bd52e54213">http://git.postgresql.org/pg/commitdiff/b6bc481d5540a3ad0d39db1e9881e6bd52e54213</a></li> <li>Partially roll back overenthusiastic SSI optimization. When a regular lock is held, Steve Singer can use that in lieu of a predicate lock to detect rw conflicts; but if the regular lock is being taken by a subtransaction, we can't assume that it'll commit, so releasing the parent transaction's lock in that case is a no-no. Kevin Grittner <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/fbc0d07796bcae8b2ee4b09ed236877338c95130">http://git.postgresql.org/pg/commitdiff/fbc0d07796bcae8b2ee4b09ed236877338c95130</a></li> <li>Fix bug in propagating ALTER TABLE actions to typed tables. We need to propagate such actions to all typed table children of a given type, not just the first one. Noah Misch <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/0bd155cbf2543cdead70b6e6390e9260035e1468">http://git.postgresql.org/pg/commitdiff/0bd155cbf2543cdead70b6e6390e9260035e1468</a></li> <li>Make psql use pg_table_size instead of pg_relation_size on 9.0+ servers. Per discussion, pg_table_size() is a more helpful number than pg_relation_size(). Bernd Helmle, reviewed by Susanne Ebrecht and me. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/cba9cd419270a9b7f442877e21685ac0de5730b3">http://git.postgresql.org/pg/commitdiff/cba9cd419270a9b7f442877e21685ac0de5730b3</a></li> <li>Truncate the predicate lock SLRU to empty, instead of almost empty. Otherwise, the SLRU machinery can get confused and think that the SLRU has wrapped around. Along the way, regardless of whether we're truncating all of the SLRU or just some of it, flush pages after truncating, rather than before.

This used to work, but since PGCLIENTENCODING is now a connection option variable, pg_upgrade would prevent it. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/1eb2231fc46bbfa85b47c19d88f72162b323aa51">http://git.postgresql.org/pg/commitdiff/1eb2231fc46bbfa85b47c19d88f72162b323aa51</a></li> <li>Add collation support on Windows (MSVC build). There is not yet support in initdb to populate the pg_collation catalog, but if that is done manually, the rest should work. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/11745364d074f3a7ee54c98fad55cfb5c5149326">http://git.postgresql.org/pg/commitdiff/11745364d074f3a7ee54c98fad55cfb5c5149326</a></li> </ul> <p>Tom Lane a pouss&eacute;&nbsp;:</p> <ul> <li>Revise the API for GUC variable assign hooks. The previous functions of assign hooks are now split between check hooks and assign hooks, where the former can fail but the latter shouldn't. Aside from being conceptually clearer, this approach exposes the "canonicalized" form of the variable value to guc.c without having to do an actual assignment. And that lets us fix the problem recently noted by Bernd Helmle that the auto-tune patch for wal_buffers resulted in bogus log messages about "parameter "wal_buffers" cannot be changed without restarting the server". There may be some speed advantage too, because this design lets hook functions avoid re-parsing variable values when restoring a previous state after a rollback (they can store a pre-parsed representation of the value instead). This patch also resolves a longstanding annoyance about custom error messages from variable assign hooks: they should modify, not appear separately from, guc.c's own message about "invalid parameter value". <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/2594cf0e8c04406ffff19b1651c5a406d376657c">http://git.postgresql.org/pg/commitdiff/2594cf0e8c04406ffff19b1651c5a406d376657c</a></li> <li>Fix collations when we call transformWhereClause from outside the parser. Previous patches took care of assorted places that call transformExpr from outside the main parser, but I overlooked the fact that some places use transformWhereClause as a shortcut for transformExpr + coerce_to_boolean. In particular this broke collation-sensitive index WHERE clauses, as per report from Thom Brown. Trigger WHEN and rule WHERE clauses too. I'm not forcing initdb for this fix, but any affected indexes, triggers, or rules will need to be dropped and recreated. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/d8d429890d6aa0246e28faa187a55cb0c65efd6e">http://git.postgresql.org/pg/commitdiff/d8d429890d6aa0246e28faa187a55cb0c65efd6e</a></li> <li>Fix SortTocFromFile() to cope with lines that are too long for its buffer. The original coding supposed that a dump TOC file could never contain lines longer than 1K. The folly of that was exposed by a recent report from Per-Olov Esgard. We only really need to see the first dozen or two bytes of each line, since we're just trying to read off the numeric ID at the start of the line; so there's no need for a particularly huge buffer. What there is a need for is logic to not process continuation bufferloads. Back-patch to all supported branches, since it's always been like this. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/1471a147f09f737511945ac59ca3162469d1a0c0">http://git.postgresql.org/pg/commitdiff/1471a147f09f737511945ac59ca3162469d1a0c0</a></li> <li>Fix plpgsql's issues with dropped columns in rowtypes in 8.4 branch. This is a back-patch of commit dcb2bda9b7042dbf43f876c94ebf35d951de10e9 of Aug 6 2009, which fixed assorted cases in which plpgsql would fail to cope with composite types that contain any dropped columns. Per discussion, this fix has been out in 9.0 for long enough to make it improbable that it creates any new bugs, so this is a low-risk fix. To make it even lower risk, I did not back-patch the changes in execQual.c, but just accepted the duplication of code between there and tupconvert.c. The added files tupconvert.h and tupconvert.c match their current states in HEAD. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/5d3853a7fa40b28b44b14084863fd83a188c9a9e">http://git.postgresql.org/pg/commitdiff/5d3853a7fa40b28b44b14084863fd83a188c9a9e</a></li> <li>Modernize dlopen interface code for FreeBSD and OpenBSD. Remove the hard-wired assumption that __mips__ (and only __mips__) lacks dlopen in FreeBSD and OpenBSD. This assumption is outdated at least for OpenBSD, as per report from an anonymous 9.1 tester. We can perfectly well use HAVE_DLOPEN instead to decide which code to use. Some other cosmetic adjustments to make freebsd.c, netbsd.c, and openbsd.c exactly alike. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/73d9a908140e709b4cb12a8d2257a11baaec974f">http://git.postgresql.org/pg/commitdiff/73d9a908140e709b4cb12a8d2257a11baaec974f</a></li> <li>Tweaks for SSI out-of-shared memory behavior. If we call hash_search() with HASH_ENTER, it will bail out rather than return NULL, so it's redundant to check for NULL again in the caller. Thus, in cases where we believe it's impossible for the hash table to run out of slots anyway, we can simplify the code slightly. On the flip side, in cases where it's theoretically possible to run out of space, we don't want to rely on dynahash.c to throw an error; instead, we pass HASH_ENTER_NULL and throw the error ourselves if a NULL comes back, so that we can provide a more descriptive error message. Kevin Grittner <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/56c7140ca813ba4c7ecb122a1d2b1268e705d092">http://git.postgresql.org/pg/commitdiff/56c7140ca813ba4c7ecb122a1d2b1268e705d092</a></li> <li>Add an example of WITH (UPDATE RETURNING) INSERT to the INSERT ref page. Per a discussion with Gavin Flower. This barely scratches the surface of potential WITH (something RETURNING) use cases, of course, but it's one of the simplest compelling examples I can think of. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/8ad58279fa75636b776e4c648e1ffc7079a2c7d9">http://git.postgresql.org/pg/commitdiff/8ad58279fa75636b776e4c648e1ffc7079a2c7d9</a></li> <li>Avoid extra whitespace in the arguments of &lt;indexterm&gt;. As noted by Thom Brown, this confuses the DocBook index processor; it fails to merge entries that differ only in whitespace, and sorts them unexpectedly as well. Seems like a toolchain bug, but I'm not going to hold my breath waiting for a fix. Note: easiest way to find these is to look for double spaces in HTML.index. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/dca30da3433c40b5f92f1704c496cda052decef9">http://git.postgresql.org/pg/commitdiff/dca30da3433c40b5f92f1704c496cda052decef9</a></li> <li>Modify initdb to complain only when no usable system locales are found. Per discussion, the original behavior seems too noisy. But if things are so broken that none of the locales reported by "locale -a" are usable, that's probably worth warning about. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/d4c810d570e71b021c93e3ee3ea4ab18af4a053d">http://git.postgresql.org/pg/commitdiff/d4c810d570e71b021c93e3ee3ea4ab18af4a053d</a></li> <li>Avoid an unnecessary syscache lookup in parse_coerce.c. All the other fields of the constant are being extracted from the syscache entry we already have, so handle collation similarly. (There don't seem to be any other uses for the new function at the moment.) <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/c5ff3ff49229e8fb7da0e46b463bfc9b12219078">http://git.postgresql.org/pg/commitdiff/c5ff3ff49229e8fb7da0e46b463bfc9b12219078</a></li> <li>Tweak collation setup for GIN index comparison functions. Honor index column's collation spec if there is one, don't go to the expense of calling get_typcollation when we can reasonably assume that all GIN storage types will use default collation, and be sure to set a collation for the comparePartialFn too. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/1766a5b63a950a667ed39c25256156bf366eb43c">http://git.postgresql.org/pg/commitdiff/1766a5b63a950a667ed39c25256156bf366eb43c</a></li> <li>Fix make_greater_string to not have an undocumented collation assumption. The previous coding worked only if ltproc-&gt;fn_collation was always either DEFAULT_COLLATION_OID or a C-compatible locale. While that's true at the moment, it wasn't documented (and in fact wasn't true when this code was committed...). But it only takes a couple more lines to make its internal caching behavior locale-aware, so let's do that. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/466dac8656c11317b91c1a4bfd5cfca4508cba94">http://git.postgresql.org/pg/commitdiff/466dac8656c11317b91c1a4bfd5cfca4508cba94</a></li> <li>Clean up minor collation issues in indxpath.c. Get rid of bogus collation test in match_special_index_operator (even for ILIKE, the pattern match operator's collation doesn't matter here, and even if it did the test was testing the wrong thing). Fix broken looping logic in expand_indexqual_rowcompare. Add collation check in match_clause_to_ordering_op. Make naming and argument ordering more consistent; improve comments. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/69f1d5fe1456229aeea3096c372eb24cedc7d597">http://git.postgresql.org/pg/commitdiff/69f1d5fe1456229aeea3096c372eb24cedc7d597</a></li> <li>Don't show unusable collations in psql's \dO command. "Unusable" collations are those not matching the current database's encoding. The former behavior inconsistently showed such collations some of the time, depending on the details of the pattern argument. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/7c76906b7e24d9ea94a2b0e33396ebcac600437d">http://git.postgresql.org/pg/commitdiff/7c76906b7e24d9ea94a2b0e33396ebcac600437d</a></li> <li>Adjust collation determination rules as per discussion. Remove crude hack that tried to propagate collation through a function-returning-record, ie, from the function's arguments to individual fields selected from its result record. That is just plain inconsistent, because the function result is composite and cannot have a collation; and there's no hope of making this kind of action-at-a-distance work consistently. Adjust regression test cases that expected this to happen. Meanwhile, the behavior of casting to a domain with a declared collation stays the same as it was, since that seemed to be the consensus. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/a19002d4e5da028ff7280554b281e402c609898b">http://git.postgresql.org/pg/commitdiff/a19002d4e5da028ff7280554b281e402c609898b</a></li> <li>Remove collate.linux.utf8.sql's assumptions about ".utf8" in locale names. Tweak the test so that it does not depend on the platform using ".utf8" as the extension signifying that a locale uses UTF8 encoding. For the most part this just requires using the abbreviated collation names "en_US" etc, though I had to work a bit harder on the collation creation tests. This opens the door to using the test on platforms that spell locales differently, for example ".utf-8" or ".UTF-8". Also, the test is now somewhat useful with server encodings other than UTF8; though depending on which encoding is selected, different subsets of it will fail for lack of character set support. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/f89e4dfa755b9c9be9c19f7c65cff50d47b4f33a">http://git.postgresql.org/pg/commitdiff/f89e4dfa755b9c9be9c19f7c65cff50d47b4f33a</a></li> <li>Fix ILIKE to honor collation when working in single-byte encodings. The original collation patch only fixed the multi-byte code path. This change also ensures that ILIKE's idea of the case-folding rules is exactly the same as str_tolower's. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/00f11f419caa873b44d70071d4ade0b8c75e7f36">http://git.postgresql.org/pg/commitdiff/00f11f419caa873b44d70071d4ade0b8c75e7f36</a></li> <li>Clean up overly complex code for issuing some related error messages. The original version was unreadable, and not mechanically checkable either. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/9a8b73147c07e02e10e0d0a34aa99d72e3336fb2">http://git.postgresql.org/pg/commitdiff/9a8b73147c07e02e10e0d0a34aa99d72e3336fb2</a></li> <li>Teach regular expression operators to honor collations. This involves getting the character classification and case-folding functions in the regex library to use the collations infrastructure. Most of this work had been done already in connection with the upper/lower and LIKE logic, so it was a simple matter of transposition. While at it, split out these functions into a separate source file regc_pg_locale.c, so that they can be correctly labeled with the Postgres project's license rather than the Scriptics license. These functions are 100% Postgres-written code whereas what remains in regc_locale.c is still mostly not ours, so lumping them both under the same copyright notice was getting more and more misleading. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/1e16a8107db9a50435b39e09c6f9c52c45e63e1a">http://git.postgresql.org/pg/commitdiff/1e16a8107db9a50435b39e09c6f9c52c45e63e1a</a></li> <li>Insert dummy "break"s to silence compiler complaints. Apparently some compilers dislike a case label with nothing after it. Per buildfarm. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/7aa3f1d08292d43b983075e190eee964c389e347">http://git.postgresql.org/pg/commitdiff/7aa3f1d08292d43b983075e190eee964c389e347</a></li> <li>Add some more mapping macros for Microsoft wide-character API.

This is needed only in 9.1 because only 9.0 had this and no one is upgrading from a 9.0 beta to 9.0 anymore. We basically don't backpatch 9.0 beta fixes at this point. <a target="_blank" href="http://git.postgresql.org/pg/commitdiff/82a4f370735130418738f8cf0fb9155b1cff5e2b">http://git.postgresql.org/pg/commitdiff/82a4f370735130418738f8cf0fb9155b1cff5e2b</a></li> <li>Have pg_upgrade properly preserve relfrozenxid in toast tables.
