Topic: New App no dynos on Heroku

I am trying to create a new heroku app but when i do

    heroku create

and i check it on the Heroku server it shows that is does not have web processes or PostgreSQL database. i have been trying to get one added but i cant figure how to do this.

On the command line when i do

    heroku ps -a my_new_app

i don't get any thing else.

What can I do to get my dynos?
