Fly Postgres, managed by Supabase

From the Supabase blog:

Fly's current Postgres offering is unmanaged. This means that you're responsible for handling scaling, point-in-time backups, replication, major version upgrades, etc. We'll run Fly's managed Postgres, which means that we do all that for you, and you can concentrate on building.

Fly and Render are the two alternatives to Heroku I hear mentioned most often, but as much as I love Heroku as a platform to run my application code, being able to trust my data with its managed Postgres add-on is what has always set it apart from the competition. I've heard less-than-encouraging reports about Render's managed Postgres capabilities and reliability, so it's interesting to see a major vendor partner with Fly to check this box.

I wonder how Craig Kierstens at CrunchyData would compare this coupling to their own offering. We reached out to Craig for comment but did not receive a response by press time.
