Wouldn't all the subsequent triggers fail also in such a case?  (For
that matter, wouldn't the existing implementation of the initial check
fail?)  I can't see a reason to expend code to avoid failing here.  It's
not very sensible to be able to create an FK on a table you don't have
read permission for.
