[bitnami/postgres-ha] persistence.size not being respected

Name and Version

bitnami/postgres-ha:9.2.4

What steps will reproduce the bug?

Set persistence.size to 20Gi and install the helm chart.

I've tested with a values.yaml and --set and neither work.

Are you using any custom parameters or values?

persistence:
  size: 20Gi

and tried

--set persistence.size=20Gi

What is the expected behavior?

Volume claim should use specified size, in this case it should be 20 Gigabytes.

What do you see instead?

Instance requests an 8Gi PVC which does not work on vultr (they have a 10 Gig minimum)
