From AWS to Hetzner: Managed RDS (Equivalent of RDS/Postgres) in Hetzner

We are spending (really!) too much in AWS: Azure or GC would be the same, so we're thinking of a drastic change and move (back) to Hetzner (which respect DNSH by the way, something our customer are requesting a lot).

We are on Docker Swarm (works perfectly), no knowledge of Kubernetes: what we are missing in Hetzner is the managed Postgres DB (and the managed Kafka).

Any suggestion on how to fill the gap? are there external company offering managed DB on hetzner?
