pg_restore -d password athentication failed

[Kristina Magwood <kristina@xxxxxxxxxxxxxx>]

Hi,
I are trying to upgrade from Postgresql
v7.3 Cygwin environment  to 8.0.1 on a plain Windows environment.
 So, far, I can get most of the data transferred, but I cannot get
the large objects.  Perusing the net, I got a hint that I must use
the -d dbname with the pg_restore utility.  Unfortunately, I keep
getting the error message:

        pg_restore:
[archiver (db)] connection to database "test3" failed: FATAL:
 password authentication failed for user "admin_user"

     The "test3"
database can be accessed with admin_user with no problems using psql.

        What
am I doing wrong?
