Thread: ALTER DEFAULT PRIVILEGES FOR ROLE

ALTER DEFAULT PRIVILEGES FOR ROLE

From
"Hilbert, Karin"

After a database was updated by the application, a schema dump showed the following default privilege statements:

--
-- Name: DEFAULT PRIVILEGES FOR SEQUENCES; Type: DEFAULT ACL; Schema: public; Owner: gitlab_dbo
--

ALTER DEFAULT PRIVILEGES FOR ROLE <dbowner> IN SCHEMA public REVOKE ALL ON SEQUENCES  FROM <dbowner>;
ALTER DEFAULT PRIVILEGES FOR ROLE <dbowner> IN SCHEMA public GRANT SELECT,USAGE ON SEQUENCES  TO <appuser>;


--
-- Name: DEFAULT PRIVILEGES FOR TABLES; Type: DEFAULT ACL; Schema: public; Owner: <dbowner>
--

ALTER DEFAULT PRIVILEGES FOR ROLE <dbowner> IN SCHEMA public REVOKE ALL ON TABLES  FROM <dbowner>;
ALTER DEFAULT PRIVILEGES FOR ROLE <dbowner> IN SCHEMA public GRANT SELECT,INSERT,DELETE,UPDATE ON TABLES  TO <appuser>;

Why would you want to revoke all privileges from the dbowner?
It actually had granted the privileges to PUBLIC, but I revoked those privileges & changed it to the app account.


What is the difference between these statements?:
ALTER DEFAULT PRIVILEGES FOR ROLE <dbowner> IN SCHEMA public GRANT ...  TO <appuser>;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ... TO <appuser>;

You would have to ask the application developer.

This seems to be a continuation of your previous post. It would seem you 
and the application developer need to have a head to head and agree on 
what the privilege/permissions policy for this application/database 
needs to be.

The first is keyed to a ROLE, the second to a SCHEMA.
