Createuser does not use the CREATE USER command. It updates the
system tables directly. This enables it to be used to specify a user id,
which CREATE USER does not allow. However, it also allows inconsistencies
to arise, as here. So createuser can put in user names that CREATE USER
cannot and that GRANT does not recognise.
