No, he's right: if we detect EOF then we'll close the socket.
However, not doing so wouldn't be an improvement.  I believe the
socket would still be read-ready so you'd have an infinite loop.

What I'd suggest doing is checking for PQstatus(conn) == CONNECTION_BAD,
or else directly rechecking PQsocket() each time, rather than assuming
the socket is still there.
