commit    1ed42e50e9636f5c9c86c679afee9200ca4e2323
Author:   Thomas Munro <tmunro@postgresql.org>
Date:     Mon May 06 03:02:41 2019 +0000
First released in: 12.0, 9.6.14, 10.9, 11.4

    Probe only 127.0.0.1 when looking for ports on Unix.
    
    Commit c0985099, later adjusted by commit 4ab02e81, probed 0.0.0.0
    in addition to 127.0.0.1, for the benefit of Windows build farm
    animals.  It isn't really useful on Unix systems, and turned out to
    be a bit inconvenient to users of some corporate firewall software.
    Switch back to probing just 127.0.0.1 on non-Windows systems.
    
    Back-patch to 9.6, like the earlier changes.
