Can I suggest that instead of this
# If you would like to use a database, there are two options:
# - (recommended) Deploy and maintain a database and pass the connection
# details to Kong via the `env` section.
# - You can use the below `postgresql` sub-chart to deploy a database
# along-with Kong as part of a single Helm release.
Can we show an example configuration for external database. I think the actually use case of this chart will be using an already configured postgres/cassandra database rather than the dependent postgres chart. I ask for a sample section of this configuration several days ago. I am almost at the point of writing my own chart for this but that will be duplication. @hbagdi @traines
