pg_restore in postgresql for restoring users

I am testing a backup of a postgres database.  It was backed up using a Fc option and I am using pg_restore to restore the database.  The original database is on a web site and I am restoring to a local database for test purposes.  I use a command like pg_restore -d fsn postgresql-fsn-7* to do the restore. Spot checking, the relations and data is restored, but the users are not.  How do I get the users to restore? Here is the tail of the error messages:
