They're not supposed to (indeed cannot). pg_restore is supposed to arrange
for references to large-object OIDs to be updated to the new values,
however. I believe it looks in columns of types OID and LO --- if you
stored your references in plain int columns, that was a mistake.

If you're using the -o option simply because you think you need it for
blobs, you don't need it.

Looks like you have blobs to me: that entry wouldn't even be there,
otherwise.
