Ah, that makes more sense.

Probably because you've created and deleted a lot of tables (does your
app use temp tables a lot?). If you aren't good about vacuuming the
system catalogs then you're going to get table bloat. If you're using
something pre-7.4 then you may get index bloat even if you *are*
vacuuming regularly :-(.

My suggestions are to update to 7.4, if you're not there already
(if you are, you may need to do VACUUM FULL and REINDEX to get rid
of the bloat); then adopt a stricter regime of routine vacuuming.
And check your FSM settings.
