Since Postgres just stores its data in Unix files, you can put a
database on anything that Unix thinks is a (non-read-only) filesystem.
I'd be a tad concerned about the longevity of a database on DVD; aren't
DVDs rated to support only about 10000 write cycles on any given block?
But for a short term, mostly-reading kind of scenario it'd probably
work. To be on the safe side, you might want to move pg_log to a plain
magnetic storage medium via a symlink --- that file gets rewritten a
large number of times per block.

AFAICS, oids have nothing to do with it.
