What does it say? The wiki page says it is a loose estimate, however, unusually larger tbloat and/or wastedbytes might be an indication. Of course, if you can afford it, a good old VACUUM FULL ANALYZE VERBOSE would tell you how many pages were reclaimed while rewriting the table. Otherwise, VACUUM VERBOSE on both the established DB and a backup/restore on a fresh DB also provide a helpful comparison of how many pages are used for suspected tables. -- Guillaume Cottenceau -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
