I'm going to make a point here that might be contentious: you are asking for Heroku. Heroku is going away because it no longer works as a business.
We are not Heroku. It is ok for you to not like what we're doing. We're building something different. We've never even _said_ we were a Heroku alternative, we just liked their UX for deploying apps and decided to roll with something similar.
While I can't agree with melony on buildpacks (shipping OCI containers straight from our CI to Fly has been a game changer), I do agree on the importance of fully-managed databases.
Our app has two components, a backend on Heroku and distributed frontend on Fly. The backend relies on a managed database, and I have not had to touch it in 6 years. Heroku does a great job providing confidence that the managed database will Just Work. The current Fly Postgres offering doesn't provide this confidence.
I also agree about the importance of fully managed databases!
We shipped "automated" Postgres because we couldn't get any fully managed DB providers to pay attention to us when we were small. I expect we'll have an option running on Fly infrastructure in the next six months.
