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
