I'd not expect to use a FULL vacuum as part of routine maintaince.
Normally, tables like this will grow until they reach some steady state
and then stay there. 14MB seems a bit big for something that you'd
expect to fit in 200KB though. Autovacuum is enabled by default in 8.3,
but has it been disabled for some reason here?
A useful thing to post would be the output of a VACUUM VERBOSE on this
table when it's grown for a day. It may give some clue as to what's
going on.
