Hm, the physical table sizes aren't very different, which suggests that
the problem must lie with the indexes. Unfortunately, VACUUM in 7.3
doesn't tell you anything about indexes if it doesn't have any dead rows
to clean up. Could you look at pg_class.relpages for all the indexes
of this table, and see what that shows?
