OS: Windows XP Pro SP2

RAM: 2GB
DB: PostgreSQL 8.3beta1, compiled by Visual C++ build 1400
I've come to the conclusion that it seems like a deadlock occurs when
dropping a column in a table the same moment that table is autovacuumed.
Example:
ALTER TABLE bondetail DROP COLUMN btw; (user=gino, 16252 records)
deadlocks with
VACUUM ANALYZE public.bondetail; (user=postgres)
If you wait a very long time, it goes on, the quick method is to cancel
the VACUUM command.
If you need some more info, let me know.
