 PostgreSQL can be accessed via port 5432 on the following DNS name from within your cluster:
-{{ template "fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
+{{ template "postgresql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
 
 To get your user password run:
 
-    PGPASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "fullname" . }} -o jsonpath="{.data.postgres-password}" | base64 --decode; echo)
+    PGPASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "postgresql.fullname" . }} -o jsonpath="{.data.postgres-password}" | base64 --decode; echo)
 
 To connect to your database run the following command (using the env variable from above):
 
-   kubectl run {{ template "fullname" . }}-client --rm --tty -i --image postgres \
+   kubectl run {{ template "postgresql.fullname" . }}-client --rm --tty -i --image postgres \
    --env "PGPASSWORD=$PGPASSWORD" \{{- if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}

 Note: Since NetworkPolicy is enabled, only pods with label
-{{ template "fullname" . }}-client=true"

 will be able to connect to this PostgreSQL cluster.
