Removes the PGRST_DB_SCHEMA variable which is public by default now.
Removes the PGRST_DB_ANON_ROLE variable, because using the authenticator role or even a superuser is very bad practice.
Replaces the postgres superuser with app_user, because using a superuser to connect to postgres is very bad practice.
