There's an old open transaction somewhere that's possibly still able to see those rows. Look for idle sessions in pg_stat_activity. I don't remember at the moment whether prepared-but-uncommitted transactions can hold back reclaiming dead data, but look into pg_prepared_xacts as well. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
