Upgrade the operator with the following command:
helm upgrade --namespace stackgres stackgres-operator \ --values my-operator-values.yml \ https://stackgres.io/downloads/stackgres-k8s/stackgres/0.9.3/helm/stackgres-operator.tgz
Upgrade of an operator can serve two purpose:
After the upgrade completes any new cluster that will be created, will be created with the new updated components. For existing clusters, there are two mechanisms in order to update components: in-place restart and reduced-impact restart. Both procedures are essentially the same but reduced-impact restart allow to restart a cluster with minimal throughput reduction for read-only connections (we will not apply draining here) or for read-write connections when a single node clusters is used.
For more details please see the cluster restart section
