The documentation already says prominently that roles and users are the same thing. If you're fooling with CREATE ROLE without having read any of that, I'm not sure that an error message will help.
I am talking about consistency here. Most people are not going to think a role is a user, at least not initially since it is a new feature. All I was saying was that the error message was a little confusing.
