Hi all,
I am trying to clean our database tuples with a manual vacuum but it's not working any help

"n_dead_tup" 74 17 1 1 6 8 6 8 16 9

thanks
Ben

Check for long running transactions. Vacuum can only clean up dead rows if there are no transactions running that could possibly need to see those old rows. The following query will show all currently running transactions, in order of transaction age along with an additional column to show their runtime.

SELECT *, now() - xact_start AS xact_runtime FROM pg_stat_activity WHERE state <> 'idle' ORDER BY xact_start;
