Hi. I have installed the postgres operator and distribution using helm following the instructions on Install with Helm - Percona Operator for PostgreSQL. Now that the pods are all up and running, I was wondering how I could interact with the cluster since most of the ways that this is done in the documentation, at least as far as I can tell, is done through modifying the deploy/cr.yaml file. In particular, I need to implement the issuing of tls certificates because the client demands it.
