It won't notice until someone runs ANALYZE on that table. autovacuum should notice that it's necessary and run but might not run promptly enough for your purposes. You might have to run analyze within your function. Before 8.3 it still wouldn't get replanned until you started a new session but 8.3 is more clever. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's 24x7 Postgres support! -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
