Are the user running postmaster and the owner of the data files the
same? Can you reproduce this problem with either the basic or NT
service setup as described in the README?

I was looking for a patch. Instead of the above, what about the attached
*untested* patch?
Someone should figure out why Cygwin link() fails in this situation,
but rename() succeeds. If so and it makes sense, then I will post a
patch to pgsql-patches.

Did you replace the postmaster symlink to postgres.exe with a copy of
postgres.exe? For example:
$ rm /usr/bin/postmaster
$ cp /usr/bin/postgres.exe /usr/bin/postmaster.exe
If so, then this explains the above.
