Pushed.
That leaves just walreceiver and postgres_fdw in need of WaitEventSet
improvements along these lines. The raw ingredients for that were
present in earlier patches, and I think Horiguchi-san had the right
idea: we should use the libpq event system to adjust our WES as
appropriate when it changes the socket underneath us. I will leave
this CF entry open a bit longer in case he would like to post an
updated version of that part (considering Tom's feedback[1]). If not,
we can close this and try again in the next cycle.
