Обсуждение: Database locks

I'm having a bear of a time with an application where one thread seems
to be keeping a lock on a table after it's supposed to release it.

select count(*) from pg_locks gives:
6816

Is there any way to get the list of locks by transation id or some
other datum to indicate which was first, or to figure out which is the
lock that is holding everything else back?

Perhaps get some stats on the rows with granted=f to see what seems to be
blocking the most people.
