Hi,
since updateting postgres to 7.1 i get the followin mails from the
do.maintenance cron job:

NOTICE:  Cache reference leak: cache pg_operator (15), tuple 666 has count 1
NOTICE:  Cache reference leak: cache pg_operator (15), tuple 664 has count 1
NOTICE:  Cache reference leak: cache pg_operator (15), tuple 98 has count 1

I have no idea what that means....
