Ishould not remove those hard links when using "pg_upgrade --link" option. 

As long as those old files still have hard links in the old data
directory, they are not going to go away.

Note that if you're using tablespaces, you need to clear out the
appropriate tablespace subdirectories, not only the old data
directory proper.
