When I am logged into my Linux DB server as the 'postgres' user, I can
run the shell command 'createuser <user_name>' and that shows me the
following:
# createuser cmennens
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) y
Shall the new role be allowed to create more new roles? (y/n) y
Does what I displayed above create a an account that can do
administrative tasks like creating/deleting users, changing their
passwords, etc, but can't hose the system catalogs or do other serious
damage? If what I did doesn't, should I do this using the 'CREATEROLE'
option manually in PostgreSQL?

I also noticed that I created a database called 'ide' in PostgreSQL as
the 'postgres' super user and I am trying to change the owner of the
database to me <cmennens> and when I run the following command, I
don't get an error but the owner doesn't appear to change for some
reason. What am I doing wrong?
ide=# \c ide
psql (8.4.4)
You are now connected to database "ide".
ide=# ALTER DATABASE ide OWNER TO cmennens;
ALTER DATABASE
ide=# \dt
List of relations
Schema | Name | Type | Owner
--------+-------+-------+----------
public | users | table | postgres
(1 row)
Any ideas if I am missing something here?
Thank you very much for all your support so far!
