One other option is to shut the database down competely, and then do a copy
of the file system the new server.  I have done this when I need to move a
very large database to a new server.  I can copy 500GB's in a couple of
hours, where restoring my large databases backups would take 10+ hours.
Just make sure you are keeping postgres at the same version level.
