Also made the same fix to int8smaller(), though there wasn't a symptom,

foolish choices (ie, using nested-loop plans) on never-yet-vacuumed tables.
This is a hack, of course. Keeping accurate track of these statistics
would be a cleaner solution, but it's far from clear that it'd be worth
the cost of doing so. In any case we're not going to do that for 6.5.
In the meantime, this quick hack provides a useful performance improvement
in the regression tests and in many real-world scenarios.

Previously, localtime() rotated a date with a day of month field which
exceeded the actual range into the next months, masking the fact that
a bad date had been specified.
Regression tests pass.

This patch solves above bugs.

necessary in order to ensure that a pg_dump dump of user-defined operators

provoking a 'Buffer Leak' notice message in one case. See my mail to

Not something to try during beta phase.
