== Angewandte Patches ==Tom Lane pushed:
- Fix assorted bugs in GIN's WAL replay logic. 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.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=4016bdef8aded77b4903c457050622a5a1815c16- 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.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=09130e5867d49c72ef0f11bef30c5385d83bf194- Remove some unnecessary tests of pgstat_track_counts. We may as
well make pgstat_count_heap_scan() and related macros just count
whenever rel->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.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f4d242ef94730c447d87b9840a40b0ec3371fe0f- 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.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=71d24466fb84bf51c479dcc85b52a0c2b71b9c50- 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.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=07f1264dda0e776a7e329b091c127059bce8cc54- Fix recent changes to not break non-IPV6-aware systems.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9771125c18c5746be57a55cfc31340f5311fca2c- 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.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=48c7d9f6ff99714495b7d6d2ebc44fbbe992cc8f- 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.

- Accept 'public' as a pseudo-role name in has_table_privilege() and
friends to see if a particular privilege has been granted to PUBLIC.
The issue was reported by Jim Nasby. Patch by Alvaro Herrera, and
reviewed by KaiGai Kohei.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=d0f876ca8ccb7dc8820302543b114014b7bac090Peter Eisentraut pushed:
- Mention the default pg_ctl wait time in the -t option documentation
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=ceb5b787c6fcfbb8667f3b0254d2f2796cee20e2- Fix makefile logic to not break the build when xgettext is missing.
xgettext is only required when make init-po is run manually; it is
not required for a build. The intent to handle that was already
there, but the ifdef's were in the wrong place.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=30e749dece0e6502d4dd0a3b2892eab61f8c073b- 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.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=402e11913fe05a7523828554cc2de3f1eb982d9c- Document (compositeval).* field selection syntax.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=80ada4c0dbc877d494f7c8886fdaebda0fbbe0bc- Complete the documentation of the USAGE privilege for foreign
servers. The GRANT reference page failed to mention that the USAGE
privilege allows modifying associated user mappings, although this
was already documented on the CREATE/ALTER/DROP USER MAPPING pages.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=9f2d7f6e2de23ecc1cfdd4172e23bd8b949fbcd2- Support MergeAppend plans, to allow sorted output from append
relations. 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. Original patch by Greg Stark, with
further hacking by Hans-Jurgen Schonig, Robert Haas, and Tom Lane.
- Change references to SQL/XML:2003 to :2008 and renumber sections
accordingly

- Applied patch by Itagaki Takahiro to fix incorrect status
calculation in ecpglib. Instead of parsing the statement just as ask
the database server. This patch removes the whole client side track
keeping of the current transaction status.

reports it is related to mutex failure: http://archives.postgresql.org/pgsql-hackers/2010-09/msg00790.php"
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=23177114c6f4f12d313d453e9153daf80c94c70bMagnus Hagander pushed:
- Fix low-risk potential denial of service against RADIUS login.
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.
http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=0e7f7071e893bb171150e53271404b0819a40669- Fix msvc build for localized versions of Visual C++. Look only at
the non-localized part of the output from "vcbuild /?", which is
used to determine the version of Visual Studio in use. Different
languages seem to localize different amounts of the string, but we
assume the part "Microsoft Visual C++" won't be modified.
