+-- If PostgREST is continually returning a 503, it's often because the base

+-- 1. Ensure the authenticator role has permission to assume the anon and authenticated roles
+GRANT anon TO authenticator;
+GRANT authenticated TO authenticator;

+-- 2. Ensure authenticator can access the public schema
+GRANT USAGE ON SCHEMA public TO authenticator;

+-- 3. In some setups, the API explicitly needs the 'service_role' granted to authenticator as well
+GRANT service_role TO authenticator;
