That's an interesting one.  The only theory that comes to mind is that
you've got multiple versions of Postgres installed on your machine,
and when the postmaster tries to launch a subprocess, the wrong copy
of postgres.exe is being selected for some reason.  Or possibly you
updated in place and didn't restart the postmaster?
