We're usually using Bitnami's Helm charts [1], [2] to deploy PostgreSQL into our K8S clusters. They also have -ha variants that might fit your needs, though I haven't tested them myself. Be aware, that you'll get a single-master-multiple-replica, so you still only have one Postgres-instance actually *writing* data. As long as most of the traffic is reading traffic, that might just work well; if you have a lot of writing traffic, you will be limited by the master pod, the node it is running on, and of course the underlying PVC. If you need multi-master, you might have a look at CockroachDB [3] which mostly Postgres-compatible.
