record object itself, rather than relying on a second OID argument to be
correct. This patch just changes the function behavior and not the
catalogs, so it's OK to back-patch to 8.0. Will remove the now-redundant
second argument in pg_proc in a separate patch in HEAD only.
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.
Most of these are harmless (e.g. the ruleutils stuff), but there
is at least one actual bug here: if you create a trigger named
"%sfoo", pg_dump will read uninitialized memory and fail to dump
the trigger correctly.
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).
which induced bug #1597 in addition to having several other misbehaviors
(like labeling the dump with a completion time having nothing to do with
reality). Instead just print out the desired strings where RestoreArchive
was already emitting the 'PostgreSQL database dump' and
'PostgreSQL database dump complete' strings.
assuming comparison of atttypid is sufficient. In a dropped column
atttypid will be 0, and we'd better check the physical-storage data
to make sure the tupdescs are physically compatible.
I do not believe there is a real risk before 8.0, since before that
we only used this routine to compare successive states of the tupdesc
for a particular relation. But 8.0's typcache.c might be comparing
arbitrary tupdescs so we'd better play it safer.
deferred triggers: either one can create more work for the other,
so we have to loop till it's all gone. Per example from andrew@supernews.
Add a regression test to help spot trouble in this area in future.
while completing execution of the cursor's query. Otherwise we get wrong
answers or even crashes from non-volatile functions called by the query.
Per report from andrew@supernews.

assuming that all operators scalarineqsel is used for have binary-
compatible datatypes on both sides ... which is very wrong of course.

exit. Without this, operations triggered during backend exit (such as
temp table deletions) won't be counted ... which given heavy usage of
temp tables can lead to pg_autovacuum falling way behind on the need
to vacuum pg_class and pg_attribute. Per reports from Steve Crawford
and others.
