5bd59b9c0a Document that errors are not output by log_statement (was they were in
8.0), and add as suggestion to use log_min_error_statement for this
purpose.  I also fixed the code so the first EXECUTE has it's prepare,
rather than the last which is what was in the current code.  Also remove
"protocol" prefix for SQL EXECUTE output because it is not accurate.

Backpatch to 8.1.X.

0a87394956 Fix the torn-page hazard for PITR base backups by forcing full page writes
to occur between pg_start_backup() and pg_stop_backup(), even if the GUC
setting full_page_writes is OFF.  Per discussion, doing this in combination
with the already-existing checkpoint during pg_start_backup() should ensure
safety against partial page updates being included in the backup.  We do
not have to force full page writes to occur during normal PITR operation,
as I had first feared.

3651a3e6fb Support the syntax
CREATE AGGREGATE aggname (input_type) (parameter_list)
along with the old syntax where the input type was named in the parameter
list.  This fits more naturally with the way that the aggregate is identified
in DROP AGGREGATE and other utility commands; furthermore it has a natural
extension to handle multiple-input aggregates, where the basetype-parameter
method would get ugly.  In fact, this commit fixes the grammar and all the
utility commands to support multiple-input aggregates; but DefineAggregate
rejects it because the executor isn't fixed yet.
I didn't do anything about treating agg(*) as a zero-input aggregate instead
of artificially making it a one-input aggregate, but that should be considered
in combination with supporting multi-input aggregates.

defe93463c Make the world safe for full_page_writes. Allow XLOG records that try to
update no-longer-existing pages to fall through as no-ops, but make a note
of each page number referenced by such records.  If we don't see a later
XLOG entry dropping the table or truncating away the page, complain at
the end of XLOG replay.  Since this fixes the known failure mode for
full_page_writes = off, revert my previous band-aid patch that disabled
that GUC variable.

0fcc3c2f1d Repair a low-probability race condition identified by Qingqing Zhou.
If a process abandons a wait in LockBufferForCleanup (in practice,
only happens if someone cancels a VACUUM) just before someone else
sends it a signal indicating the buffer is available, it was possible
for the wakeup to remain in the process' semaphore, causing misbehavior
next time the process waited for an lmgr lock.  Rather than try to
prevent the race condition directly, it seems best to make the lock
manager robust against leftover wakeups, by having it repeat waiting
on the semaphore if the lock has not actually been granted or denied
yet.

cc39aca7d4 Fix similar_escape() so that SIMILAR TO works properly for patterns involving
alternatives ("|" symbol).  The original coding allowed the added ^ and $
constraints to be absorbed into the first and last alternatives, producing
a pattern that would match more than it should.  Per report from Eric Noriega.

I also changed the pattern to add an ARE director ("***:"), ensuring that
SIMILAR TO patterns do not change behavior if regex_flavor is changed.  This
is necessary to make the non-capturing parentheses work, and seems like a
good idea on general principles.

Back-patched as far as 7.4.  7.3 also has the bug, but a fix seems impractical
because that version's regex engine doesn't have non-capturing parens.

98c6c966bc Update AIX FAQ:
At any rate, here's a revision to CVS HEAD to reflect some changes by
myself and by Seneca Cunningham for the AIX FAQ.  It touches on the
following issues:

1.  memcpy pointer patch for dynahash.c

2.  AIX memory management, which can, for 32 bit cases, bite people
    quite unexpectedly...

49a7610c36 Fix an ancient oversight in btree xlog replay. When trying to determine if an
upper-level insertion completes a previously-seen split, we cannot simply grab
the downlink block number out of the buffer, because the buffer could contain
a later state of the page --- or perhaps the page doesn't even exist at all
any more, due to relation truncation.  These possibilities have been masked up
to now because the use of full_page_writes effectively ensured that no xlog
replay routine ever actually saw a page state newer than its own change.
Since we're deprecating full_page_writes in 8.1.*, there's no need to fix this
in existing release branches, but we need a fix in HEAD if we want to have any
hope of re-allowing full_page_writes.  Accordingly, adjust the contents of
btree WAL records so that we can always get the downlink block number from the
WAL record rather than having to depend on buffer contents.  Per report from
Kevin Grittner and Peter Brant.

Improve a few comments in related code while at it.

a81e281636 Revert my best_inner_indexscan patch of yesterday, which turns out to have
had a bad side-effect: it stopped finding plans that involved BitmapAnd
combinations of indexscans using both join and non-join conditions.  Instead,
make choose_bitmap_and more aggressive about detecting redundancies between
BitmapOr subplans.

898eb25431 Fix best_inner_indexscan to actually enforce that an "inner indexscan" use
at least one join condition as an indexqual.  Before bitmap indexscans, this
oversight didn't really cost much except for redundantly considering the
same join paths twice; but as of 8.1 it could result in silly bitmap scans
that would do the same BitmapOr twice and then BitmapAnd these together :-(

c6e81aeef3 Fix EXPLAIN so that it can drill down through multiple levels of subplan
when trying to locate the referent of a RECORD variable.  This fixes the
'record type has not been registered' failure reported by Stefan
Kaltenbrunner about a month ago.  A side effect of the way I chose to
fix it is that most variable references in join conditions will now be
properly labeled with the variable's source table name, instead of the
not-too-helpful 'outer' or 'inner' we used to use.
