[Windows] Pg_Restore on 8.1.5 and so on...

I am trying to restore from a pg_dump.  Pg_restore is doing some
strange behaviour.

If I open a CMD shell console and execute pg_restore, nothing is
showed.  If I try to do a "with sense" pg_restore, nothing is showed in
spite of I have put --verbose option.

This is my complete command:

pg_restore --verbose --file=c:\dbt.dump --host=127.0.0.1
--username=masteruser --password

Somebody with the same behaviour ?.  I am running 8.1.5 on a Windows XP
sp2 workstation.

Thanks in advance.
