Keycloak high availibility

Hello all, can we use keycloak codecentric helm charts for high availibility. Actually i am new to keycloak and i have to setup HA cluster using helm in on prem k8s.I have tested codecentric helm chart it by default creates one posgtress db pod and a keycloak pod. But i am not sure if 1 db gets down what will be the impact. what if we use multiple replicas of db and in this will the data be replicated in all the databases and keycloak instances as well. Any advises would be highly appreciated.

Review this lovely repo [1] and article [2] for references.
