I updated the changelog entry. I have no idea how to test it, but if you have an idea I can implement it.

@aried3r How much do you care about test coverage for this, considering the difficulty in setting up multiple databases in CI?

I haven't yet needed to test multi-db Rails setups on CI myself, so I have to ask naively, shouldn't it be – at least for PostgreSQL – "just" another call do createdb?

I don't want to test Rails itself, but if there was even a single test that confirms that two DBs are being used, I'd appreciate it.

Could we also add a little bit of documentation to the README?

Any plans to merge this to master?

@n-studio Hey, sorry for the delay! Do you think you could:

1. Add some docs in the readme.
2. Setup a second database in CI and some example showing that multiple DBs are used.

Until those things are completed, I'm going to put this in draft state just to indicate that there's work to be done before a final review.
