You will want to use the 8.1 version of pg_dump/pg_dumpall to connect to
the 7.4 version of postgresql to do the restore. There is pretty good
docs on it here:
http://www.postgresql.org/docs/8.2/static/backup.html
You will want to be careful though, some things have changed since 7.4.
IIRC, timestamp/timestamptz changes, and float changes as well.
