Hi. I've just discovered the check_postgres utility and am running all the tests against my database. The "last_analyze" test comes out critical - many tables unanalyzed for 8 weeks. I am running PostgreSQL 8.4.4 with default autovacuum settings. I thought autovacuum was supposed to take care of running vacuum and analyze. Per "last_analyze", 9 out of my 100 tables have been analyzed within the last 24 hours. Why aren't all my tables being analyzed? How do I troubleshoot this, please? Best, -at P.S. I checked the PostgreSQL logs, and in the last week, I just have three messages with "vacuum" in them: (I am running at default log levels) 2010-07-20 02:05:05 PDT ERROR: canceling autovacuum task 2010-07-20 02:05:05 PDT CONTEXT: automatic vacuum of table "mydb.pg_catalog.pg_listener" 2010-07-20 07:27:14 PDT ERROR: canceling autovacuum task 2010-07-20 07:27:14 PDT CONTEXT: automatic vacuum of table "mydb._slony_cluster.sl_event" 2010-07-20 07:27:53 PDT ERROR: canceling autovacuum task 2010-07-20 07:27:53 PDT CONTEXT: automatic vacuum of table "mydb._slony_cluster.sl_log_2" -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
