commit    40e64017f3a4f1f7547dcbc62c2dcf80511ff842
Author:   Heikki Linnakangas <heikki.linnakangas@iki.fi>
Date:     Wed Apr 13 19:20:31 2011 +0000
First released in: 9.1.0, 9.0.4

    On HP/UX, the structs used by ioctl(SIOCGLIFCONF) are named differently
    than on other platforms, and only IPv6 addresses are returned. Because of
    those two issues, fall back to ioctl(SIOCGIFCONF) on HP/UX, so that it at
    least compiles and finds IPv4 addresses. This function is currently only
    used for interpreting samehost/samenet in pg_hba.conf, which isn't that
    critical.
