I have used custom format archieve in pg_dump.
I have used the following command in plpgsql function to insert the image.
lo_import(xlogopath)After I inserted one image more records are created in pg_largeobject and pg_largeobject_metadata tables other than the OID returned from lo_import

object(s), since plain-text pg_dump format prints the large object
contents in hex. I'd take a second look at exactly how you inserted
the large objects; it seems highly likely that you inserted them multiple
times or bloated their contents somehow.
