5d0d60efe6 Make standalone backends ignore pg_database.datallowconn, so that there 
is a way to recover from disabling connections to all databases at once.

ecbc6dd3e9 Alter the signature for encoding conversion functions to declare the 
output area as INTERNAL not CSTRING.  This is to prevent people from
calling the functions by hand.  This is a permanent solution for the
back branches but I hope it is just a stopgap for HEAD.

0d8cdcfe88 GCC 4.0 includes a new warning option, -Wformat-literal, that emits 
a warning when a variable is used as a format string for printf()
and similar functions (if the variable is derived from untrusted
data, it could include unexpected formatting sequences). This
emits too many warnings to be enabled by default, but it does
flag a few dubious constructs in the Postgres tree. This patch
fixes up the obvious variants: functions that are passed a variable
format string but no additional arguments.

This patch fixes a bug in pg_dump (triggers with formatting sequences
in their names are not dumped correctly) and some related pg_dump
code that looks dubious; cleanups for more harmless instances have
been applied to more recent branches.

8f54b05551 This patch fixes a bug in the error message emitted by pg_restore on an 
incorrect -F argument: write_msg() expects its first parameter to be a
"module name", not the format string.

2cfb3b6d4d Repair two TIME WITH TIME ZONE bugs found by Dennis Vshivkov. Comparison 
of timetz values misbehaved in --enable-integer-datetime cases, and
EXTRACT(EPOCH) subtracted the zone instead of adding it in all cases.
Backpatch to all supported releases (except --enable-integer-datetime code
does not exist in 7.2).

aa4762e7c8 Don't try to constant-fold functions returning RECORD, since the optimizer 
isn't presently set up to pass them an expected tuple descriptor.  Bug has
been there since 7.3 but was just recently reported by Thomas Hallgren.

ce49ae9041 Previous "64-bit fix" for intagg didn't actually work. This is already 
fixed properly in CVS tip, but we need a band-aid for back branches.

acb42e9cb9 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.

0b83c1f272 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.

best to just touch the places that actually have a problem.

c57bcb7b2c 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.

a7e5e2fe74 When returning type "record", replace use of pgresultGetTupleDesc 
with ReturnSetInfo->expectedDesc. This allows custom datatypes
(e.g. from tsearch2) to be returned at runtime. Previous behavior
depended on the type oid to match between the remote and local
database, which obviously doesn't work well for custom types.
