That will try to connect via TCP, so your problem might just be that you
didn't start the 7.0 postmaster with "-i" and/or didn't copy over your
old pg_hba.conf config file.  (See nearby thread about PGAccess
connect problems.)

If it's not that, we'll need to know exactly why it's failing to
connect.  There should be an error message coming out someplace ...
