The bug related to the detection of Windows and temporary paths for
pg_upgrade's server.c has been fixed as of dc57366, so attached is the
remaining rebased piece as perl2host has been recently removed.

Do others have an opinion about a backpatch of the bugfix?  Nobody has
complained about that since pg_upgrade exists, so I have just done the
change on HEAD.
