I agree that would be a welcome enhancement. As a workaround, you can create a function owned by a superuser (or any other user with the "createrole" privilege) using "security definer" that provides a simple "create user" capability and makes sure that the created user does not have the createdb privilege. The user/role that should be able to create new roles doesn't need the createrole privilege at all then. All it needs is the execute privilege on the function. Thomas
