! #if defined(TCP_KEEPIDLE)
! /* TCP_KEEPIDLE is the name of this option on Linux and *BSD */
if (setsockopt(port->sock, IPPROTO_TCP, TCP_KEEPIDLE,
(char *) &idle, sizeof(idle)) < 0)
{
elog(LOG, "setsockopt(TCP_KEEPIDLE) failed: %m");
return STATUS_ERROR;
}
! #elif defined(TCP_KEEPALIVE_THRESHOLD)

Side note: Windows has something with a different set of options:
