pg_restore won't create database

Here's what I'm trying to do:

$ pg_dump -Fc -b -f backup.pgd test_backup_db
$ dropdb test_backup_db
DROP DATABASE
$ pg_restore -C -d test_backup_db backup.pgd
pg_restore: [archiver (db)] connection to database "test_backup_db" failed:
FATAL:  database "test_backup_db" does not exist

Here is what the man pages for -C say:

-C
--create
 Create the database before restoring into it. (When this option is used,
the database named with -d is used only to issue the initial CREATE
DATABASE command. All data is restored into the database name that appears
in the archive.)

What am I doing wrong?  Thank you for the help.
