hack/setup_external_dev_services: Improve postgresql installation

Browse Source 
The postgresql helm chart requires the cluster to provide a PersistentVolume
and places a PersisentVolumeClaim for this.
Ensure that the cluster provides PersistentVolumes.

Also set volumePermissions.enabled=true which helps to fix Permission denied
when trying to create the data directory in the PV mount directory
if the PV's permissions are not open enough:

# Note: The chart mounts the PV at persistence.mountPath,
# which defaults to /bitnami/postgresql and creates a directory /data in it.
# If it has no permission to create it, this error happens:
# mkdir: cannot create directory ‘/bitnami/postgresql/data’: Permission denied

# Adding --set volumePermissions.enabled=true helps:
