Failure to connect to Postgres DB when using existing secret

[RxJcollins]

I am trying to deploy this chart with using an existing secret for the DB connection info. However, the pod(s) will not start because of failing to connect for the 'postgres' user. When I look in the DB pod, I see a value written to the environment variables for a password for the DB user 'postgres' however it is not the password that is in my sealed secret. I have even attempted to override it using values from the bitnami/chart/values.yaml to know success. It seems the secret that keeps getting deployed to my namespace is the one created by the chart and does not contain the keys and values from my existing secret.
