There already is a defined API for this, namely PQisBusy().
In any case, I rather concur with the XXX comment: busy-waiting like
this sucks. The correct way to do this is to get the socket numbers for
the connections (via PQsocket), wait for any of them to be read-ready
according to select() (or for the timeout to elapse, assuming that we
think that behavior is good), then cycle through PQconsumeInput() and
PQisBusy() on each connection. See
