And I see the age of databases being correctly decreased to the freeze min age (plus however many transactions it took to do the vacuuming work). So I'm still at a loss on why is it failing to advance the datfrozenxid of your database. Please let me have a look at this query result while connected to that database: select relname, relfrozenxid from pg_class where relkind in ('r', 't'); You can change the relname to oid if showing the table names is problematic for you. -- Alvaro Herrera http://www.amazon.com/gp/registry/5ZYLFMCVHXC Al principio era UNIX, y UNIX habló y dijo: "Hello world\n".
