Error of dump OID datatype - Mailing list pgsql-bugs

Dear sir=20
    I use postgres 7.0.3 non-commercial version. I have some error will rep=
ort about OID datatype bug/error. The problem is I can not export file(OID =
datatype-text file) from table that was dumped by old database which I back=
up after it was transfered from old server to new server.=20

    Well, When I use command such as
"testDB=3D#SELECT lo_export(history.file,'/usr/local/etc/webscan/output/aaa=
') from history where login =3D 'chong' and ip=3D'202.0.0' and s_date=3D'20=
01-02-06';"

result is :
ERROR:  Relation 22369 does not exist
    What does it mean?

Thank you=20
