How to restrict table rights to specific tables for a specific custom event, although that user inherits from admin

I have a user called "user1" inherited from admin (who has all access to all tables). Is there a way in postgres to make all tables visible when logged in as admin. But when you are logged in as user1 (although user1 inherited from admin), only the visible few tables need to be visible (so that he can open them, he cannot open a table he cannot see)
