Yes, that will work, but you have to SET ROLE before creating the table. > 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? No, that is impossible. But I don't understand the motivation: If you want that, why would you want a "table_owner" role? If you don't want user B to be able to drop user A's table, why don't you have each user be the owner of his tables? Yours, Laurenz Albe
