Yes, I agree that it makes sense to add a note, even if
allow_in_place_tablespaces is a developer option.  I have added the
following paragraph in the docs:
+        A full path of the symbolic link in <filename>pg_tblspc/</filename>
+        is returned. A relative path to the data directory is returned
+        for tablespaces created with
+        <xref linkend="guc-allow-in-place-tablespaces"/> enabled.

Another thing that was annoying in the first version of the patch is
the useless call to lstat() on Windows, not needed because it is
possible to rely just on pgwin32_is_junction() to check if readlink()
should be called or not.

This leads me to the revised version attached.  What do you think?
