Yes but I'm trying to understand the difference because the default
'postgres' user that is auto-configured to have 'SUPERUSER',
'CREATEDB', & 'CREATEROLE' grants. I'm trying to understand if those
are redundant grants or if there is a reason PostgreSQL developers
grant the 'postgres' user with SUPERUSER, CREATEDB, & CREATEROLE.
Seems to me logically that if a someone is a superuser, then they
should be able to CREATEDB & CREATEROLE, no? So why would the
'postgres' user need those additional attributes?


postgres=# \du
            List of roles
 Role name  | Attributes  | Member of
------------+-------------+-----------
 cmennens   | Superuser   | {}
 postgres   | Superuser   | {}
            : Create role
            : Create DB
