The recommended procedure is to use 8.2.3's pg_dump, not 8.0's, to
connect to the old database. And no, you don't need --ignore-version
for that, because pg_dump knows how to talk to previous server versions.
That switch is there only for connecting to a database of a _newer_
version that pg_dump's, and it's generally problematic because sometimes
an older pg_dump doesn't know how to read the newer system catalogs.
