helm chart postgresql install, helm uninstall - config svc remains

[josepowera]

We first install postgres with helm install, than uninstall with helm uninstall

After uninstall is completed, there remains a service installed with installname-config

helm install postgresacoustid /acoustid-helm-charts/postgresql --set users.superuser.password=secretpassword --set users.replication.password=secretpassword --set clusterName=postgresacoustid --set resources.limits.cpu=0.5 --set resources.limits.memory=1024Mi

helm uninstall postgresacoustid
release "postgresacoustid" uninstalled

kubectl get svc |grep config
postgresacoustid-config                 ClusterIP   None            <none>        <none>      3m44s
