FWIW, I doubt that this is something we need to worry about and I
suspect that there is no action item here. dblink and WAL receivers
do their stuff so as the main backend code does not link with libpq,
and I doubt that we'd ever want to enter in the territory where
FRONTEND becomes a thing in libpq.
Of course, I may prove wrong.
