Feel free to insist on that, if you want to make dead certain that
updatable views don't make it into 8.4 ;-)

My recollection of the discussion two years ago is that we concluded
that WITH CHECK OPTION is simply not implementable using a rule-based
infrastructure, because of the multiple-evaluation problem.  Perhaps
it could be done with some kind of extension to the constraint-checking
logic, but I freely admit I don't see how to do it in any detail.
That seems like something to tackle later on.
