independently of whether the struct tm tm_zone member exists.
Also run autoheader, which seems not to have been done lately;
it added about three more things to pg_config.h.in than I was expecting...
example from Rao Kumar. This is a very corner corner-case, requiring
a minimum of three closely-spaced database crashes and an unlucky
positioning of the second recovery's checkpoint record before you'd notice
any problem. But the consequences are dire enough that it's a must-fix.
Ross Reedstrom, a couple months back) and to detect timezones that are
using leap-second timekeeping. The unknown-zone-name test is pretty
heuristic and ugly, but it seems better than the old behavior of just
switching to GMT given a bad name. Also make DecodePosixTimezone() a
tad more robust.

If you need another include file for Windows, then add it; don't go
messing with the semantics of every other port's include files.
Win32 port is now called 'win32' rather than 'win'

new /port/opendir.c routines
disable GUC unix_socket_group on Win32
convert some keywords.c symbols to KEYWORD_P to prevent conflict
create new FCNTL_NONBLOCK macro to turn off socket blocking
create new /include/port.h file that has /port prototypes, move

the type OID and typmod of the underlying base type. Per discussions
a few weeks ago with Andreas Pflug and others. Note that this behavioral
change affects both old- and new-protocol clients.
This makes no difference for existing uses, but allows SelectSortFunction()
and pred_test_simple_clause() to use indexscans instead of seqscans to
locate entries for a particular operator in pg_amop. Better yet, they can
use the SearchSysCacheList() API to cache the search results.
dropped. The simplest fix for INSERT/UPDATE cases turns out to be for
preptlist.c to insert NULLs of a known-good type (I used INT4) rather
than making them match the deleted column's type. Since the representation
of NULL is actually datatype-independent, this should work fine.
I also re-reverted the patch to disable the use_physical_tlist optimization
in the presence of dropped columns. It still doesn't look worth the
trouble to be smarter, if there are no other bugs to fix.
Added a regression test to catch future problems in this area.
where the table contains dropped columns. If the columns are dropped,
then their types may be gone as well, which causes ExecTypeFromTL() to
fail if the dropped columns appear in a plan node's tlist. This could
be worked around but I don't think the optimization is valuable enough
to be worth the trouble.
detected during buffer dump to be labeled with the buffer location.
For example, if a page LSN is clobbered, we now produce something like
ERROR: XLogFlush: request 2C000000/8468EC8 is not satisfied --- flushed only
to 0/8468EF0
CONTEXT: writing block 0 of relation 428946/566240
whereas before there was no convenient way to find out which page had
been trashed.
dead xlog segments are not considered part of a critical section. It is
not necessary to force a database-wide panic if we get a failure in these
operations. Per recent trouble reports.
