Thinkful Unit 2 Lesson 4 instructions

in Step 2 you download a file called dvdrental.zip
It might not be clear that you need to also do
'createuser -s postgres'
and
psql -U postgres
CREATE DATABASE dvdrental;
Step 3: 'Type the following command: unzip dvdrental.tar' should say 'unzip dvdrental.zip'

Could not initialize heroku-aspen-migrate: no such file to load -- heroku/client/pgbackups
Are you attempting to install a Rails plugin? If so, use the following:
