But aptible doesn't have managed postgres. I still have to do all the work of setting up a database and managing backups, upgrades, etc. The only thing aptible brings to the table is single tenant hardware and encryption by default. I can just get that from Amazon. Am I missing something about aptible? I don't understand the attraction although it does look fancy

Healthcare Blocks is another option: https://www.healthcareblocks.com

Aptible absolutely has managed postgres, and it's great. I'm using it at this very second.

Where can I find out more? All I see on their marketing site is "database containers" which I interpreted as little more than a container that happens to run a database, not as something that manages backups, point-in-time restoration, multi-az failover, upgrades, and all the other things that RDS has built in that many folks would otherwise prefer to have an (expensive) postgres specialist setup and manage for you.

Dang, sorry about that: https://www.aptible.com/enclave/
