The problem was that the table needed a "vacuum full". It was a large
table and had done a massive update. It is not that it was blocked, but
that it was just taking a very long time.
Is there a way to tell what tables have locks on them?
SELECT * from pg_locks ;
(version 7.4 and above at least, don't have an install earlier than that).
