commit    bb3051e4c2d7b42516d55925edefb4934b902374
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Thu Apr 07 19:14:44 2011 +0000
First released in: 9.1.0, 8.2.21, 8.3.15, 8.4.8, 9.0.4

    Modernize dlopen interface code for FreeBSD and OpenBSD.
    
    Remove the hard-wired assumption that __mips__ (and only __mips__) lacks
    dlopen in FreeBSD and OpenBSD.  This assumption is outdated at least for
    OpenBSD, as per report from an anonymous 9.1 tester.  We can perfectly well
    use HAVE_DLOPEN instead to decide which code to use.
    
    Some other cosmetic adjustments to make freebsd.c, netbsd.c, and openbsd.c
    exactly alike.
