I'm not sure, exactly. I think what'll happen is that if you're
trying to read data from the remote server, the connection will
eventually break instead of hanging forever, but I'm not exactly sure
what that'll look like at the libpq level. I'm not sure what effect
it'll have on an idle connection.
