If so, can they be > retrieved? The reset timestamp of each table entry is unfortunately not stored, look at PgStat_StatTabEntry to see what's stored. Well we could have that as well, it is important to be careful that the reset is updated for all tables. Note that the timestamp reset happens in pgstat.c actually. What you could do for now is to use a wrapper on top of pg_stat_reset_single_table_counters() that calls now() and stores timestamp on a custom table storing (oid,timestamp). -- Michael -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
