Re: Date range for pg_stat_all_tables?

Hi -

Thanks for below.

On 9.1 with postgresql.conf left at defaults, what period of time does a
query on pg_stat_all_tables cover?

Let's say my database has been running for exactly one year.

I then issue SELECT relname, n_tup_ins FROM pg_stat_all_tables;

Do the results show me inserts for the last 7 days? 30 days? all time?..

I don't see the answer to this in
http://www.postgresql.org/docs/9.1/static/monitoring-stats.html (or maybe
it is there and I am not understanding).

Thanks once again,
Ronit
