Or we just broke EOF detection on Windows sockets in general. It might be
worth checking if the problem appears on the client side; that is, given a
psql running on Windows, do local-equivalent-of-kill-9 on the connected
backend, and see if psql notices. (Hm, although if it's idle psql wouldn't
notice until you next try a command, so it might be hard to tell. Maybe
kill -9 while the backend is in process of a long query?)
