Let me show you my statistics, that confuses me even in terms of this discussion. What am I doing. 1. Create a database *highload*. 2. Execute *select xact_commit from pg_stat_database where datname = 'highload'* from neighbouring database (so that xact_commit is counted to that neighbour) and receive 0. 3. Connect to database from several different clients and get +1 to xact_commit for each connection. 4. Wait for 1 min (several times) and get +2 each minute - so this is autovacuum works. 5. Start executing simple select *select * from pg_user* Each select gives me +4, +5, +6. In pgadmin - even +19. So the first question. 1. Why autovacuum gives +2 2. Why select gives +4 an more ? -- View this message in context: http://postgresql.1045698.n5.nabble.com/Postgres-9-1-statistics-in-pg-stat-database-tp5744283p5769528.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
