Aside from that, this looks quite invasive for back-patching, and the
number of bug reports so far suggest that we should be worried about
more breakage appearing later.
However, that leaves us in a situation where we have no back-patchable
fix for a bug which causes queries to return the wrong answer, which
is not a great situation.
Is there a smaller fix that we could commit to fix the bug?
