if available (which it usually should be), during processing of Bind

log_min_error_statement logging for extended query protocol.
sin_port in the returned IP address struct when servname is NULL. This has
been observed to cause failure to bind the stats collection socket, and
could perhaps cause other issues too. Per reports from Brad Nicholson
and Chris Browne.
that conflict with the OID that we want to use for the new database.
This avoids the risk of trying to remove files that maybe we shouldn't
remove. Per gripe from Jon Lapham and subsequent discussion of 27-Sep.
timezone actually has a daylight-savings rule. This avoids breaking
cases that used to work because they went through the DecodePosixTimezone
code path. Per contrib regression failures (mea culpa for not running
those yesterday...). Also document the already-applied change to allow
GMT offsets up to 14 hours.
input routines. Remove the former "DecodePosixTimezone" function in favor of
letting the zic code handle POSIX-style zone specs (see tzparse()). In
particular this means that "PST+3" now means the same as "-03", whereas it
used to mean "-11" --- the zone abbreviation is effectively just a noise word
in this syntax. Make sure that all named and POSIX-style zone names will be
parsed as a single token. Fix long-standing bogosities in printing and input
of fractional-hour timezone offsets (since the tzparse() code will accept
these, we'd better make 'em work). Also correct an error in the original
coding of the zic-zone-name patch: in "timestamp without time zone" input,
zone names are supposed to be allowed but ignored, but the coding was such
that the zone changed the interpretation anyway.
example SET TIME ZONE 'america/new_york' works now. This seems a good
idea on general user-friendliness grounds, and is part of the solution
to the timestamp-input parsing problems I noted recently.
modules; the first try was not usable in EXEC_BACKEND builds (e.g.,
Windows). Instead, just provide some entry points to increase the
allocation requests during postmaster start, and provide a dedicated
LWLock that can be used to synchronize allocation operations performed
by backends. Per discussion with Marc Munro.
one of the program's core data structures, make use of the existing
ability to selectively exclude TOC items by ID. Slightly more code but
much less likely to create future maintenance problems.
1) pgwin32_waitforsinglesocket(): WaitForMultipleObjectsEx now called with
finite timeout (100ms) in case of FP_WRITE and UDP socket. If timeout occurs
then pgwin32_waitforsinglesocket() tries to write empty packet goes to
WaitForMultipleObjectsEx again.
2) pgwin32_send(): add loop around WSASend and pgwin32_waitforsinglesocket().
The reason is: for overlapped socket, 'ok' result from
pgwin32_waitforsinglesocket() isn't guarantee that socket is still free,
it can become busy again and following WSASend call will fail with
WSAEWOULDBLOCK error.

rows --- if the surrounding query queued any trigger events between the rows,
the events would be fired at the wrong time, leading to bizarre behavior.
Per report from Merlin Moncure.
This is a simple patch that should solve the problem fully in the back
branches, but in HEAD we also need to consider the possibility of queries
with RETURNING clauses. Will look into a fix for that separately.
