    log_connections: yes
    log_min_messages: DEBUG5
    log_min_error_statement: DEBUG5
    max_wal_senders: 10

install

helm install myrelease bitnami/postgresql --values cfg.yaml

this will create config Map:

 k get configMap myrelease-postgresql-extended-configuration -o yaml
apiVersion: v1
data:
  override.conf: |-
    log_connections=yes
    log_min_messages=DEBUG5
    log_min_error_statement=DEBUG5
    max_wal_senders=10
kind: ConfigMap
metadata:
  annotations:
    meta.helm.sh/release-name: myrelease
    meta.helm.sh/release-namespace: default
  creationTimestamp: "2023-05-03T09:13:58Z"
  labels:
    app.kubernetes.io/component: primary
    app.kubernetes.io/instance: myrelease

  namespace: default
  resourceVersion: "914998"
  uid: 7921bfad-11f5-410f-95ed-772f1a5d693a

and mount it into

cat /opt/bitnami/postgresql/conf/conf.d/override.conf
