Agreed. I spent some time trying to do it better, with results
shown at [1]. If we adopt that idea, then the executor's support
for CaseTestExpr will go away, so there's little point in pursuing
that half of the patch given here. However, I concluded that there's
insufficient reason to redesign CoerceToDomainValue, so we could
still push forward with that half of this patch.
