Safe-pg-migrations, ActiveRecord migrations for Postgres made safe

I have never introduced this gem here. It is a library that we use at Doctolib (if you are french, you know it. If you aren’t, it is a healthcare system for practitioners and patients, in the top 10 of the most downloaded application in France). It makes PG migrations safe, by automatically replacing unsafe versions of a migration to its safe version.

Give it a try, and tell us what you think :slight_smile:
