No, and do you really want the server stopping its processing of the
query just to go see if the client is still alive? This would slow
things down and introduce a whole new failure mode, ie, client doesn't
answer ping fast enough so its session gets aborted.
(Just for the record, PQstatus isn't a "ping" operation either.)
