Hmm. With integrated autovacuum, we could set something up to issue
vacuums separately to TOAST tables and the main table. It'd probably be
a tad easier if the toast stats are separate from the main table; and an
autovac of the main table not necessarily would invoke vacuuming the
toast table.
I'm not proposing it for 8.1 though ...
