On Windows, also call shutdown() while closing the client socket.
Further experimentation shows that commit6051857 is not sufficientwhen using (some versions of?) OpenSSL. The reason is obscure, butcalling shutdown(socket, SD_SEND) improves matters.Per testing by Andrew Dunstan and Alexander Lakhin.Back-patch as before.Discussion:https://postgr.es/m/af5e0bf3-6a61-bb97-6cba-061ddf22ff6b@dunslane.net
