For what it's worth VACUUM ANALYZE does have to take an additional lock to update the statistics. It should rarely cause any problems but it is a possibility. When you do get a good example you might want to take the contents of pg_locks at the same time as pg_stat_activity. That would at least be able to help rule out any real locks and make it clear it's really stuck on waiting for a block to become unpinned. -- greg -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
