Hello, we got a small problem with auto_vacuum: since we have some big tables which have heavy read/write access, we tried to exclude this tables from autovacuum: database1=# select vacrelid,enabled,(select relname from pg_class where oid=vacrelid) as relname from pg_autovacuum; vacrelid | enabled | relname ----------+---------+---------------------- 42041 | f | guestbook 42344 | f | forum_threads 42406 | f | forum_thread_entries 41937 | f | user_online 42255 | f | forum_fora 41570 | f | users 41694 | f | user_data (7 rows) Now it seems, that autovacuum is processing exactly this tables: 2007-07-04 22:37:05 CEST DEBUG: autovacuum: processing database "database1" 2007-07-04 22:37:06 CEST DEBUG: autovac: will VACUUM ANALYZE users 2007-07-04 22:37:06 CEST DEBUG: autovac: will VACUUM ANALYZE user_stats 2007-07-04 22:37:06 CEST DEBUG: autovac: will VACUUM ANALYZE guestbook 2007-07-04 22:37:06 CEST DEBUG: autovac: will VACUUM ANALYZE forum_fora 2007-07-04 22:37:06 CEST DEBUG: autovac: will VACUUM ANALYZE forum_threads 2007-07-04 22:37:06 CEST DEBUG: autovac: will VACUUM ANALYZE forum_thread_entries 2007-07-04 22:37:06 CEST DEBUG: autovac: will VACUUM ANALYZE user_data 2007-07-04 22:37:06 CEST DEBUG: autovac: will VACUUM ANALYZE user_online 2007-07-04 22:37:06 CEST DEBUG: vacuuming "schema1.users" 2007-07-04 22:38:39 CEST DEBUG: vacuuming "pg_toast.pg_toast_41570" 2007-07-04 22:38:47 CEST DEBUG: vacuuming "schema1.user_stats" 2007-07-04 22:49:06 CEST DEBUG: vacuuming "pg_toast.pg_toast_43602" 2007-07-04 22:51:51 CEST DEBUG: vacuuming "schema1.guestbook" 2007-07-04 23:00:38 CEST DEBUG: vacuuming "pg_toast.pg_toast_42041" 2007-07-04 23:00:43 CEST DEBUG: vacuuming "schema1.forum_fora" 2007-07-04 23:00:50 CEST DEBUG: vacuuming "pg_toast.pg_toast_42255" 2007-07-04 23:00:50 CEST DEBUG: vacuuming "schema1.forum_threads" 2007-07-04 23:01:06 CEST DEBUG: vacuuming "schema1.forum_thread_entries" 2007-07-04 23:01:50 CEST DEBUG: vacuuming "pg_toast.pg_toast_42406" 2007-07-04 23:01:54 CEST DEBUG: vacuuming "schema1.user_data" 2007-07-04 23:05:36 CEST DEBUG: vacuuming "pg_toast.pg_toast_41694" 2007-07-04 23:05:45 CEST DEBUG: vacuuming "schema1.user_online" database1=# select version(); version ----------------------------------------------------------------------------------------------------------------- PostgreSQL 8.2.4 on x86_64-pc-linux-gnu, compiled by GCC cc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21) (1 row) Any idea, what's wrong here?
