Bytea typed columns are completely separate things than large objects.  You
cannot exclude individual columns using pg_dump.

 Thanks.Then I've misunderstood large objects.  Is there document to explain large objects?  We store images in bytea column.

Large objects are a relatively old and now little-used feature of PostgreSQL that predates the bytea type:

As was mentioned, you cannot exclude individual columns with pg_dump; you have to exclude the entire table.
