I am using Kubernetes static PV to mount my Postgresql data. But I am unable to do this

Here is my YAML file where I create PV , PVC and my Postgres pod  
my data directory of Postgres located at “/var/lib/pgsql/9.3/data”

But initially, my data directory /var/lib/pgsql/9.3/data is nonempty. I already append some sample data here. I want that Kubernetes will create the volume in the same location and mount it to /mnt/data

I also provide permissions and ownership but my problem still not fixed. The same thing works fine if I use docker volume

```
apiVersion: v1
kind: PersistentVolume
metadata:
  name: task-pv-volume
  namespace: manhattan
  labels:
    type: local
spec:
  storageClassName: manual
  capacity:
    storage: 100Mi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/mnt/data"
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: task-pv-claim
  namespace: manhattan
spec:
  storageClassName: manual
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 80Mi
---
apiVersion: v1
kind: Pod
metadata:
  name: dbr-postgres
  namespace: manhattan
spec:
  volumes:
    - name: task-pv-storage
      persistentVolumeClaim:
        claimName: task-pv-claim
  containers:
    - name: task-pv-container
      image: postgresql:2.0.1
      tty: true
      volumeMounts:
        - mountPath: "/var/lib/pgsql/9.3/data"
           name: task-pv-storage
           subPath: data
           readOnly: false
  nodeSelector:
     kubernetes.io/hostname: k8s-master

```

Can anyone tell me what I am doing wrong?
