I need to run Postgres in production soon. I've used AWS RDS (MySQL) in the past, but am also considering Google Cloud SQL.

Things that seem similar in AWS:

- For major version upgrades, you need to bring up a new instance from a snapshot and catch it up with replication.

- HA failover results in a few minutes of downtime. (They claim using their SQL proxy will reduce this.)

- Lag in providing the latest Postgres versions. GCP seems to be a bit ahead of AWS here.

Is there a managed Postgres offering that you prefer? Aiven looks nice, feature-wise.
