Re: An extra error for client disconnection on Windows

Hello.

After a process termination without PQfinish() of a client,
server emits the following log message not seen on Linux boxes.

> LOG:  could not receive data from client: An existing connection was forcibly closed by the remote host.

This is because pgwin32_recv reuturns an error ECONNRESET for the
situation instead of returning non-error EOF as recv(2) does.

This patch translates WSAECONNRESET of WSARecv to an EOF so that
pgwin32_recv behaves the same way with Linux.

The attached patch does this.
