a really useful script for Heroku + Rails. Generate a db backup, download it, create a new db, import data, update database config to point at it
heroku pg:backups capture --app open-plaques-beta
curl -o db/db.dump `heroku pg:backups --app open-plaques-beta public-url`
createdb openplaques_$(date +'%Y-%m-%d')
pg_restore -d openplaques_$(date +'%Y-%m-%d') db/db.dump
sed -iE "s/openplaques_[0-9|-]*/openplaques_$(date +'%Y-%m-%d')/g" config/database.yml

Cloud9 Rails5 Heroku update
Cloud9.io has a Rails template project, but it is Rails 4
Check that it is still Rails 4:
$ rails -v
Rails 5 needs ruby 2.2.2 minimum, but I belive that Cloud9 has 2.3.0p0....just check:
$ ruby -v
Update the rails installation to 5:
$ gem install rails
