pg_restore problem when restoring big table

[RexHsu <rexhsu(at)tom(dot)com>]

Postgresql 8.0.3
Windows XP with SP2


C:\Program Files\PostgreSQL\8.0\bin>pg_restore --dbname=smedb --verbose
--ignore
-version --host=localhost --username=postgres "c:\backup2005-08-08 10
.47.06"

when it was restoring data of one big table,it returned error msg like
[custom archive] can not read data block - unexpected 1, actual 0

then I turned on debug5 mode,it gave me more detail:

2005-08-26 10:22:16 ERROR:  08P01: unexpected message type 0x58 during COPY from stdin
2005-08-26 10:22:16 CONTEXT:  COPY t_attachment, line 53: ""

Is there any problem when to restore big blob data in postgresql?

I dont know how to do now. Any help will be appreciated.
