I have fixed this to the extent that pg_dump ignores large objects,
as it is documented to do.  (It was doing that just fine, but it
failed to ignore the indexes on the large objects :-(.)

Of course what you'd really like is for a pg_dump script to save
and restore large objects along with everything else.  But there
seem to be several big problems to be solved before that can happen.
The worst is that a large object's OID will likely be recorded in
at least one other table in the database, and pg_dump is not nearly
smart enough to find and update those references...
