Suppose I have a hierarchy like this
parent
|
child
/\
/ \
/ grandchild2
/
grandchild1
and I have a validated constraint on grandchild1 and an invalid
constraint on child. What happens if I add a constraint on parent? In
my understanding, it should not attempt to revalidate the constraint on
grandchild1, because it's known valid; but I don't think I see code that
would skip validation there. That is, QueueFKConstraintValidation does
its thing unconditionally (esp. recursing to children), which seems
wrong.
