Hmm.  If you take a full backup using pg_dump -Fc, you can then use
pg_restore -l and pg_restore -L to find and selectively restore
whatever objects you want; e.g. restore the tables first, then fetch
the list of OIDs from the relevant columns and restore those
particular blobs.

But I don't think we've got a tool built into core for doing this kind
of filtering on the dump side.
