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

The size of the output file will be about twice the length of the large 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.
