Unfortunately, yes. libpq can't change the global setting of SIGPIPE
without breaking the surrounding application, but we don't want to crash
the app if the server connection has disappeared, either. So we have to
set the SIGPIPE handler and then restore it around every send().
On some platforms there might be a better way, but this is the only
portable way I know about.
