If it's just one database, then use pg_dump
(http://www.postgresql.org/docs/current/static/app-pgdump.html) to
create a database dump, then you can pipe it into psql:

psql < /path/to/dumpfile.

or use pg_restore
(http://www.postgresql.org/docs/current/static/app-pgrestore.html).

If you want to move the whole system, use pg_dumpall to dump all databases.

Thanks. No complications due the move to the higher version (8.2)?

Per usual remarks about upgrading found in installation instructions of
every release, you will need to use pg_dump that comes with the new
version to connect to the old database and run your dump, to make sure
the dump is compatible with the new version. Consult the -i option of
pg_dump. Just make a try having the new server ready. I guess you are in
a quite comfort situation because you seem to be able to run the two
machines simultaneously for a while. Be sure to use 8.2.1, just released.
