pg_restore - Windows 2000

Hello all!!

I'm in a trouble restoring a database.

System:
PostgreSQL 8.0
Windows 2000 Professional SP4

when I do pg_dump to backup mydb:

C:\Archivos de programa\PostgreSQL\8.0\bin>pg_dump -U juan --format=c
mydb > back2
Password:
pg_dump: [custom archiver] WARNING: ftell mismatch with expected position -- fte
ll used
pg_dump: [custom archiver] WARNING: ftell mismatch with expected position -- fte
ll used
pg_dump: [custom archiver] WARNING: ftell mismatch with expected position -- fte

pg_dump: [custom archiver] WARNING: ftell mismatch with expected position -- fte

the file back2 is generated and looks like good, but when I try to restore:

C:\Archivos de programa\PostgreSQL\8.0\bin>pg_restore -U juan
--format=c -d nueva back2
pg_restore: [archiver] unsupported version (1.13) in file header

Is this a bug?, from already thanks
