How to reset PG Database on Heroku?

• Step 1: heroku restart -a app_name
• Step 2: heroku pg:reset DATABASE -a app_name (no need to change the DATABASE)
• Step 3: heroku run rake db:migrate -a app_name
• Step 4: heroku run rake db:seed -a app_name (if you have seed)

One liner

heroku restart -a app_name; heroku pg:reset DATABASE -a app_name --confirm APP-NAME; heroku run rake db:migrate -a app_name
