1. Cluster is close to the stop limit. 2. Autovacuum runs, updates pg_database and advances oldestXid. Phew! 3. Crash. After recovery, oldestXid is reset to the old value, and you start getting warnings again. However, everything seems fine in pg_database, all the databases have been recently vacuumed. Does autovacuum ever run to fix that? ISTM it won't. -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com -- Sent via pgsql-committers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-committers
