The original coding was quite sloppy about handling the case where XLogReadBuffer fails (because the page has since been deleted). This would result in either "bad buffer id: 0" or an Assert failure during replay, if indeed the page were no longer there. In a couple of places it also neglected to check whether the change had already been applied, which would probably result in corrupted index contents. I believe that bug #5703 is an instance of the first problem. These issues could show up without replication, but only if you were unfortunate enough to crash between modification of a GIN index and the next checkpoint. Back-patch to 8.2, which is as far back as GIN has WAL support. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=4016bdef8aded77b4903c457050622a5a1815c16">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=4016bdef8aded77b4903c457050622a5a1815c16</a></li> <li>Fix plpython so that it again honors typmod while assigning to tuple fields. This was broken in 9.0 while improving plpython's conversion behavior for bytea and boolean. Per bug report from maizi. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=09130e5867d49c72ef0f11bef30c5385d83bf194">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=09130e5867d49c72ef0f11bef30c5385d83bf194</a></li> <li>Remove some unnecessary tests of pgstat_track_counts. We may as well make pgstat_count_heap_scan() and related macros just count whenever rel-&gt;pgstat_info isn't null. Testing pgstat_track_counts buys nothing at all in the normal case where that flag is ON; and when it's OFF, the pgstat_info link will be null, so it's still a useless test. This change is unlikely to buy any noticeable performance improvement, but a cycle shaved is a cycle earned; and my investigations earlier today convinced me that we're down to the point where individual instructions in the inner execution loops are starting to matter. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f4d242ef94730c447d87b9840a40b0ec3371fe0f">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f4d242ef94730c447d87b9840a40b0ec3371fe0f</a></li> <li>Document the DISTINCT noise word in the UNION/INTERSECT/EXCEPT constructs. I also rearranged the order of the sections to match the logical order of processing steps: the distinct-elimination implied by SELECT DISTINCT happens before, not after, any UNION/INTERSECT/EXCEPT combination. Per a suggestion from Hitoshi Harada. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=71d24466fb84bf51c479dcc85b52a0c2b71b9c50">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=71d24466fb84bf51c479dcc85b52a0c2b71b9c50</a></li> <li>Allow WITH clauses to be attached to INSERT, UPDATE, DELETE statements. This is not the hoped-for facility of using INSERT/UPDATE/DELETE inside a WITH, but rather the other way around. It seems useful in its own right anyway. Note: catversion bumped because, although the contents of stored rules might look compatible, there's actually a subtle semantic change. A single Query containing a WITH and INSERT...VALUES now represents writing the WITH before the INSERT, not before the VALUES. While it's not clear that that matters to anyone, it seems like a good idea to have it cited in the git history for catversion.h. Original patch by Marko Tiikkaja, with updating and cleanup by Hitoshi Harada. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=07f1264dda0e776a7e329b091c127059bce8cc54">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=07f1264dda0e776a7e329b091c127059bce8cc54</a></li> <li>Fix recent changes to not break non-IPV6-aware systems. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9771125c18c5746be57a55cfc31340f5311fca2c">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9771125c18c5746be57a55cfc31340f5311fca2c</a></li> <li>Improve GIN indexscan cost estimation. The better estimate requires more statistics than we previously stored: in particular, counts of "entry" versus "data" pages within the index, as well as knowledge of the number of distinct key values. We collect this information during initial index build and update it during VACUUM, storing the info in new fields on the index metapage. No initdb is required because these fields will read as zeroes in a pre-existing index, and the new gincostestimate code is coded to behave (reasonably) sanely if they are zeroes. Teodor Sigaev, reviewed by Jan Urbanski, Tom Lane, and Itagaki Takahiro. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=48c7d9f6ff99714495b7d6d2ebc44fbbe992cc8f">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=48c7d9f6ff99714495b7d6d2ebc44fbbe992cc8f</a></li> <li>Fix a passel of inappropriately-named global functions in GIN. The GIN code has absolutely no business exporting GIN-specific functions with names as generic as compareItemPointers() or newScanKey(); that's just trouble waiting to happen. I got annoyed about this again just now and decided to fix it. This commit ensures that all global symbols defined in access/gin/ have names including "gin" or "Gin". There were a couple of cases, like names involving "PostingItem", where arguably the names were already sufficiently nongeneric; but I figured as long as I was risking creating merge problems for unapplied GIN patches I might as well impose a uniform policy. I didn't touch any static symbol names. There might be some places where it'd be appropriate to rename some static functions to match siblings that are exported, but I'll leave that for another time. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=419d2374bfbc1eae562121fde31c1aa0e8a164cb">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=419d2374bfbc1eae562121fde31c1aa0e8a164cb</a></li> </ul> <p>Alvaro Herrera a pouss&eacute;&nbsp;:</p> <ul> <li>Fix typo. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=82659e0456f5c5a52a35ee41e63882c280ec2496">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=82659e0456f5c5a52a35ee41e63882c280ec2496</a></li> <li>Allow pg_ctl to register the service in either AUTO or DEMAND start type Author: Quan Zongliang.

The intent to handle that was already there, but the ifdef's were in the wrong place. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=30e749dece0e6502d4dd0a3b2892eab61f8c073b">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=30e749dece0e6502d4dd0a3b2892eab61f8c073b</a></li> <li>Remove reference.ced. This is a parsed DocBook DTD for the PSGML Emacs mode, but it hasn't been updated since we switched to DocBook 4.2 about seven years ago. Also, PSGML has deprecated this method of DTD parsing. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=402e11913fe05a7523828554cc2de3f1eb982d9c">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=402e11913fe05a7523828554cc2de3f1eb982d9c</a></li> <li>Document (compositeval).* field selection syntax. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=80ada4c0dbc877d494f7c8886fdaebda0fbbe0bc">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=80ada4c0dbc877d494f7c8886fdaebda0fbbe0bc</a></li> <li>Complete the documentation of the USAGE privilege for foreign servers.

This patch eliminates the former need to sort the output of an Append scan when an ordered scan of an inheritance tree is wanted. This should be particularly useful for fast-start cases such as queries with LIMIT.

Corrupt RADIUS responses were treated as errors and not ignored (which the RFC2865 states they should be). This meant that a user with unfiltered access to the network of the PostgreSQL or RADIUS server could send a spoofed RADIUS response to the PostgreSQL server causing it to reject a valid login, provided the attacker could also guess (or brute-force) the correct port number. Fix is to simply retry the receive in a loop until the timeout has expired or a valid (signed by the correct RADIUS server) packet arrives. Reported by Alan DeKok in bug #5687. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=0e7f7071e893bb171150e53271404b0819a40669">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=0e7f7071e893bb171150e53271404b0819a40669</a></li> <li>Fix msvc build for localized versions of Visual C++.
