commit    375cb7cfb018ba69f874cd39d2c5f28e2de6301a
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Thu Oct 19 17:26:43 2006 +0000
First released in: 8.2.0, 7.4.15, 8.0.10, 8.1.6

    Work around reported problem that AIX's getaddrinfo() doesn't seem to zero
    sin_port in the returned IP address struct when servname is NULL.  This has
    been observed to cause failure to bind the stats collection socket, and
    could perhaps cause other issues too.  Per reports from Brad Nicholson
    and Chris Browne.
