Is it possible ? The concept of the privilege system is that each database object determines what you can do with it (with an access control list). The owner of a database object can do everything with it. So I'd do it like this: Owning user (owns schema "myschema"): CREATE TABLE myschema.mytable (...); GRANT USAGE ON SCHEMA myschema TO bibi; GRANT INSERT, UPDATE, DELETE ON myschema.mytable TO bibi; Now user "bibi" can du exactly what you want.
