Hmph. Something quit and left a lock set on some table (whatever
VACUUM would've come to after pg_rules), it looks like. Could be
an artifact of the known bug in 7.0.* that shared memory state isn't
properly cleaned up when a client disconnects in the middle of a
BEGIN block. That's fixed for 7.0.3, if we ever quit arguing and
push it out the door ;-)
