Craig here from Crunchy. RDS is definitely in the spectrum of more managed, but I'd still say it's more of a spectrum. For instance to my knowledge AWS doesn't fully monitor your individual database for availability, much of their monitoring is more on a fleet/control plane level. There are cases I've heard of where your database is down and AWS simply doesn't know about it because it's not doing health checks against postgres itself. Not implying those cases are a common occurrence, but in a spectrum of how managed it is we definitely aim to be at the far end of how much we do for you on Crunchy Bridge.

Another big area is tooling we're building in to help app developers. Things like health reports for your database, built-in audit logs, simple SSO integration are just a few things that you now don't really have to think but can benefit heavily from. Overall we're a pretty big parallel to Heroku Postgres, with more to come (I wrote about some of that vision here - https://www.craigkerstiens.com/2022/05/18/unfinished-busines...).
