Moving the goal posts, aren't we?  It was not possible to find that out
at all from the pg_locks view before.  (Well, you could guess based on
the type of table locks held, but you were only guessing.)

As of CVS HEAD you *can* determine that from pg_locks, to high
probability anyway, by looking to see which VXIDs have transaction IDs
locked.
