i am 100% sure.... "SELECT pg_stat_get_db_blocks_fetched(764755937), pg_stat_get_db_blocks_hit(764755937);" gives be constantly increasing stats and "SELECT relname,heap_blks_read from pg_statio_user_tables order by heap_blks_read DESC LIMIT 15;" is still showing me all zero 4 mins into the test until i first vacuum analyze is done.... just think abt this.... if we get these stats how easily we can decide the division of tables in tablespaces.... just write a simple program which will collect the data every t mins... analyze it and move them to diff tablespaces... is there any other way of finding table usage??? thx a lot tom Himanshu __________________________________________________ Do You Yahoo!?
