I created a role named 'carlos' which is my current user account with
'superuser' grants but my question is when I look at 'postgres'
account, he has additional grants that I don't understand.
List of roles
Role name | Attributes | Member of
-----------+-------------+-----------
carlos | Superuser | {}
jmadeline | Create DB | {}
mwilshaw | Create DB | {}
postgres | Superuser | {}
: Create role
: Create DB
So from what I see above, 'carlos' is a superuser but do I need to
grant him 'CREATEROLE' & 'CREATEDB' rights along with 'SUPERUSER' or
is 'SUPERUSER' by itself good enough?
