I understand the premise, but this isn't performant enough to be used for anything but the smallest of projects. It isn't just "an extra second of overhead", it increased a 15 second test run to 15 minutes for me (on a fast fiber connection). Locally I already have Postgres installed for development, and Travis does as well. I guess this might be useful for Jenkins on EC2 in the same AZ as Heroku Postgres, but the latency is still going to be painful.
