Heroku rake db:migrate
when I run heroku rake db:migrate I keep getting:

    Migrating to CreateUsers (20110216103237)
    ==  CreateUsers: migrating ====================================================
    -- create_table(:users)

even though the Users table has already been created before. does anyone know why this might be occurring?

thanks
