Hi,
I just unstuck a bunch of my buildfarm animals. That triggered some
spurious failures (on piculet, calliphoridae, mylodon), but also one
that doesn't really look like that:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=culicidae&dt=2017-03-16%2002%3A40%3A03
with the pertinent point being:

it's possible that me killing things and upgrading caused this, but
given this is a backend running EXEC_BACKEND, I'm a bit suspicous that
it's more than that. The machine is a bit backed up at the moment, so
it'll probably be a while till it's at that animal/branch again,
otherwise I'd not have mentioned this.
Greetings,
Andres Freund
