I actually think we should just leave this alone.  There is a
limitless number of things that someone could potentially be confused
by if they fail to read the documentation, and we can't warn about all
of them.

Now, one thing we could do is add a deprecation warning, stating that
CREATEUSER may be removed in a future release, assuming we want to
eventually remove it.  But I don't think warning people that
CREATEUSER means SUPERUSER and not CREATEROLE is very helpful.
