Am facing one problem related to pg_toast table , its grown very huge upto 31GB , even am vacuuming(not full) it daily , my fsm parameters are default, can anyone tell how to decrease the size , if am firing any query on gen_bulk_20121126 its response time is very slow as compared to few days before .
For changing fsm parameters it will need restart , can anyone suggest me any other way for decreasing the size of this pg_toast tables.
