No, get_rel_name returns the relname from pg_class. What you need is in pg_namespace: namespace from relid: get_namespace_name(get_rel_namespace(relid)) relname from relid: get_rel_name(relid)))); If you're going to relation_open the rel, then you might want to use: get_namespace_name(RelationGetNamespace(rel)) and RelationGetRelationName(rel)))); -- David Rowley http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
