This looks reasonable so far.  The commit messages 
8f3ec75de4060d86176ad4ac998eeb87a39748c2 and 
1d53432ff940b789c2431ba476a2a6e2db3edf84 contain some notes about what I 
thought at the time didn't work yet.  In particular, the pg_upgrade 
tests don't support the use of Unix sockets on Windows.  (Those tests 
have been rewritten since, so I don't know what the status is.)  Also, 
the comment in pg_regress.c at remove_temp() is still there.  These 
things should probably be addressed before we can consider making this 
the default.
