Those are unused tuple slots, not tuples. They can be re-used, but they won't be reclaimed unless the page they are in is truncated from the table. > (Note :The db is vacuumed every ~5 hours ver 7.3) It would appear that you need a round of VACUUM FULL to get these tables back down to a reasonable physical size, and in future vacuum more often. Check your FSM settings too. regards, tom lane
