Ok, you caught me :-) Actually, I developed the patch thinking only on
the multi-relation TRUNCATE, with the goal of having it for 8.1. Only
after I prepared a first patch I noticed the temp-table-FKs problem.
So I don't really care if it has to wait for 8.1 because that was the
original intention anyway.

Right, that's why I did it in the first place.

Ok, turns out it wasn't that much smaller anyway :-) But really it's
only stashing a couple of foreach loops in two places, which is a fairly
trivial change; and the other important part is the modification of
heap_truncate_check_FKs and it's fairly localized anyway.
