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.
cases with binary-compatible relabeling. My first try was implicitly
assuming that all operators scalarineqsel is used for have binary-
compatible datatypes on both sides ... which is very wrong of course.
Per report from Michael Fuhr.
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.
binary-compatible relabeling of one or both operands. examine_variable
should avoid stripping RelabelType from non-variable expressions, so that
they will continue to have the correct type; and convert_to_scalar should
just use that type and ignore the other input type. This isn't perfect
but it beats failing entirely. Per example from Michael Fuhr.
when a zero-month interval is given. Per discussion with Karel.
Also, some desultory const-labeling of constant tables. More could be
done along that line.
actual number of unremoved tuples as pg_class.reltuples. The idea of
trying to estimate a steady state condition still seems attractive, but
this particular implementation crashed and burned ...
