> The docs say that REVOKE EXECUTE ... RESTRICT should 
> fail if there is a dependent constraint:
> "The RESTRICT clause specifies that the EXECUTE privilege cannot be
>  revoked if the specified routine is used in a view, trigger, or
>  constraint, and the privilege is being revoked from the owner of the
>  view, trigger, or constraint."
>  Revoking the privilege will be correctly restricted, but possibly for the wrong reason.
