Supabase

Is there some way to connect to the database as the user that owns the objects created through supabase, so that I can modify tables (ALTER TABLE) through an external tool like TablePlus?

To that end, would it be a bad idea to make the postgres user a superuser like in https://github.com/supabase/supabase/discussions/2495
