bdb2d697a7 Prevent to_char(interval) from dumping core on month-related formats 
when a zero-month interval is given.  Per discussion with Karel.

826f14f6d3 Some builds (depends on crypto engine support?) of OpenSSL 
0.9.7x have EVP_DigestFinal function which which clears all of
EVP_MD_CTX.  This makes pgcrypto crash in functions which
re-use one digest context several times: hmac() and crypt()
with md5 algorithm.

Following patch fixes it by carring the digest info around
EVP_DigestFinal and re-initializing cipher.

Marko Kreen.

13fab5b3ad Mark the text_soundex() function as "strict", to avoid crashing on NULL 
input. Also, may as well mark it "cacheable" as well. From Kris Jurka.

66bb44cf63 The result of a FULL or RIGHT join can't be assumed to be sorted by the 
left input's sorting, because null rows may be inserted at various points.

6acddf56b4 Prevent pg_ctl from being run as root. Since it uses configuration files 
owned by postgres, doing "pg_ctl start" as root could allow a privilege
escalation attack, as pointed out by iDEFENSE.  Of course the postmaster would
fail, but we ought to fail a little sooner to protect sysadmins unfamiliar
with Postgres.  The chosen fix is to disable root use of pg_ctl in all cases,
just to be confident there are no other holes.

6b3d751747 Repair possible failure to update hint bits back to disk, per 
http://archives.postgresql.org/pgsql-hackers/2004-10/msg00464.php.
I plan a more permanent fix in HEAD, but for the back branches it seems
best to just touch the places that actually have a problem.

7b0919047f Fix breakage in hashjoin from recent backpatch of left-join bug fix. 
(That's what I get for not testing the back branches *before* committing.)

44ed69c8f3 Hashed LEFT JOIN would miss outer tuples with no inner match if the join 
was large enough to be batched and the tuples fell into a batch where
there were no inner tuples at all.  Thanks to Xiaoyu Wang for finding a
test case that exposed this long-standing bug.

d0b776b2be Fix failure to guarantee that a checkpoint will write out pg_clog updates 
for transaction commits that occurred just before the checkpoint.  This is
an EXTREMELY serious bug --- kudos to Satoshi Okada for creating a
reproducible test case to prove its existence.

fbec0d7e94 Repair multiple memory leaks in getTables(), including one that could 
easily exhaust memory on databases with more than a few hundred triggers.
I don't expect any more releases of these old versions, but let's put the
fix in CVS just so it's archived.

5925377401 Fix longstanding error in _bt_search(): should moveright at top of loop not 
bottom.  Otherwise we fail to moveright when the root page was split while
we were "in flight" to it.  This is not a significant problem when the root
is above the leaf level, but if the root was also a leaf (ie, a single-page
index just got split) we may return the wrong leaf page to the caller,
resulting in failure to find a key that is in fact present.  Bug has existed
at least since 7.1, probably forever.

28afe6f8ef TestConfiguration returns int, not bool. This mistake is relatively 
harmless on signed-char machines but would lead to core dump in the
deadlock detection code if char is unsigned.  Amazingly, this bug has
been here since 7.1 and yet wasn't reported till now.  Thanks to Robert
Bruccoleri for providing the opportunity to track it down.

40faf433b0 Async_NotifyHandler must save and restore ImmediateInterruptOK. Fixes 
known problem with failure to respond to 'pg_ctl stop -m fast', and
probable problems if SIGINT or SIGTERM arrives while processing a
SIGUSR2 interrupt that arrived while waiting for a new client query.
