Hi List I'd like to setup my database in a way that only a superuser may create schemas, then grants permission to a specific user to create tables inside this schema. This should work so far with GRANT CREATE ON SCHEMA ... TO user_a. However I want the table owner not to be the user that creates the tables. Instead the owner should rather be a generic role (e.g. table_owner), and the owner should be the same over all tables of the whole database. This would work, too, if I grant membership in role table_owner to all users that may create tables. (The users must issue a SET ROLE table_owner before creating tables.) What I didn't achieve so far is making sure that user_a who created tables in schema_a cannot crete/modify tables of schema_b that were created by user_b. Do you see any way to achieve this, while still sticking to that generic owner role? Thanks a lot for your thoughts. Andy
