Korry Douglas has an EDB sponsored project called pg_migrator on
pgfoundry. I believe it works for upgrading from 8.1 to 8.2 except
for tables that use the ip address datatype. It works by just
replacing the 8.1 system catalogs with the 8.2 system catalogs. I
believe the on-disk images for 8.1 and 8.2 are the same except for the
ip address field.
