However, you probably could:
1. write a function (as a superuser) that creates users
2. let it run with the permissions of the creator
3. grant access to your target group.

You'll want to read up on the SECURITY DEFINER attributes of CREATE FUNCTION
and probably the EXECUTE command of plpgsql.

Note - I haven't tried this myself, so if it does work it would be helpful to
let the list know.
