Jan's work will become the official PG Native Win32 version so it's the one to watch/play with. Note that he's not claiming it's ready for prime time, yet, just far enough along to for folks to play with it with the expectation that most stuff will work but that there are undoubtably bugs to fix.
While it requires Cygwin to build, hopefully either the PG project or other folks will make pre-built Win32 x86 builds available once it becomes a supported platform (planned, I believe, for 7.4).
