The result is exactly the same, here...
test=# create role testrole superuser;
CREATE ROLE
test=# \du List of rolesRole name | Superuser | Create role | Create DB | Connections |
Memberof
-----------+-----------+-------------+-----------+-------------+-----------
testrole | yes | no | no | no limit |
test=# alter role testrole nosuperuser;
ALTER ROLE
test=# \du List of rolesRole name | Superuser | Create role | Create DB | Connections |
Memberof
-----------+-----------+-------------+-----------+-------------+-----------
testrole | no | no | no | no limit |
So a superuser which has not been explicitly created with "createuser"
and "create DB" privileges will become a no privilege while losing the
status superuser.
If created with the Unix command createuser, he won't.
