How auto rollback on rails work?

After git checkout:

1. Execute git checkout db/migrate
1. Get migration versions
1. Execute bundle exec rake db:migrate:down VERSION= for each version
1. Undo all changes in db/migrate/ and db/schema.rb

The flow will be less complicated if pre-checkout git hook exist

$3

- Assumes all migration are reversible
- bundle exec rake db:migrate:down VERSION=` fails silently
