Massimo pointed out some problems in my fix.  The new code is:
   if (++proc_exit_inprogress == 9)         elog(ERROR, "infinite recursion in proc_exit");   if (proc_exit_inprogress
>=9)       goto exit;      /* ----------------    *  if proc_exit_inprocess > 1, then it means that we    *  are being
invokedfrom within an on_exit() handler    *  and so we return immediately to avoid recursion.      * ----------------
 */   if (proc_exit_inprogress > 1)         return;
