HOLD ON! Do you empty them by doing something like
delete from table
with no where clause?
If so, then try truncating the table. That will clean it completely and
reclaim all the dead space, plus it's faster than delete anyway.
If that doesn't help, look at scheduling more aggressive plain vacuums
(no just autovacuum, but cron job vacuum on specific tables that you
know have a high turnover).
Vacuum full is basically admitting your regular vacuum schedule isn't /
can't be aggressive enough.
