For changing fsm parameters it will need restart , can anyone suggest me any other way for decreasing the size of this pg_toast tables.


pg_toast contains large data that won't fit in regular tuples.

this table that you're getting slow queries on, could you show us one of these slow queries with EXPLAIN ANALYZE ? if your table has grown significantly it could need a carefully chosen index to speed up these queries, or something similar.

also the output of...

    VACUUM VERBOSE pg_toast_123049508   ;

may be enlightening.
