How can I reset the counters from pg_stat_database view? I know I can reset some counters by running:

select pg_stat_reset()


but some counters like xact_commit aren't reset.

How can I do it?

I've tried also:

pg_stat_reset_shared('database')


but doesn't work.   :-(

Any ideas, please?

I could store the last counters and substract for the next time.
The solution is simple, store previous values and substract.
No need to reset anything in Postgres.
In this way meaningful stats can be obtained:

(newValue-oldValue)/numberOfSeconds
