Utility statements (which is to say anything except SELECT/INSERT/
UPDATE/DELETE) generally don't cope with parameters. The above won't
work because it's trying to substitute parameters for username_ and
password_ in the CREATE USER utility statement. You could make it work
by constructing the CREATE USER command as a string and then EXECUTE'ing
it.
(I agree this ain't ideal, but it's where we're at...)
