Okay. I applied what you'd done (with minor revisions), but we'll have
to fix up the regular indexscan API before anything can be done about
@@@. I'll take a look at that part tomorrow.

Teodor, do you have any thoughts about exactly how you'd fix @@@ ?
I suppose that the recheck-need is not really a property of specific
tuples, but of a particular query, for that case. Where would you
want to detect that?
