In 7.0, yes.  Later versions keep large objects in pg_largeobject rather
than in individual tables.  I don't recall the details of pg_dumplo, but
it's likely that it's confused by this difference.

You might try running the 7.3 pg_dump against the 7.0 server in one of
the modes that can dump large objects.  Theoretically that should work,
though I can't say I've tried it recently.
