Automatic Rollback after migrations are applied

[konsalex]

Hey folks,

Currently we ship our software, call it Acme Inc., through container images, that connect to external PG instances.

How can we work with the following scenario:

1. Users use Acme_Inc@v0.0.1
2. Migrations are executed on container init
3. Users spin up new container Acme_Inc@0.0.2
4. Migrations are applied
5. Something breaks in the logic and they decide to re-use Acme_Inc@0.0.1

Does the CLI knows that the migrations now should perform a down operation? Or are we responsible to perform this? If so, how would you recommend approaching this?

I tried to find something in the docs, but the only thing I could find was that you just keep track for versions used.
