Nonetheless, this does seem to speak to my real concern, which is
whether the patch introduces any unexpected side-effects. The code
was getting executed, whether or not it detected any FK violations,
so we can have some hope that any bizarre problems would have been
noticed.
I'll go ahead and apply it for 7.3.3.
