I recently have been working on setting up a HA Postgres Cluster on K8's... its for a pretty small DB use case and not knowing much about the world of Postgres and Databases I ended up using the Crunchy Postgres Operator which amazingly did all of the work for me... (I honestly don't know much about Patroni other then it manages the switchover to replicas during a failure)... anyway I'd recommend the Crunchy Operator... As a side note, we've found that it takes quite a while for the initial pgBackRest job to run (like 8 minutes) which seems like a lot for an empty DB, but we aren't using SSDs
