Poking at that, I find that a1a789eb5 back-patches reasonably painlessly
into v11 and v10, but trying to bring it back to 9.6 encounters a pile of
merge failures. Also, looking at the git logs shows that we did a hell
of a lot of subtle work on that code (libpqwalreceiver.c in particular)
during the v10 cycle. So I've got no confidence that successful
buildfarm/beta1 testing of the HEAD patch means much of anything for
putting it into pre-v10 branches.
Given that we've seen few if any field reports of this issue, my
inclination is to back-patch as far as v10, but not take the risk
and effort involved in going further.
