Upgrade Notices

The builtin bitnami postgresql database is no longer enabled by default in the test values or the examples. We do not recommend this configuration. For local development usage where the builtin bitnami postgresql database is desired, set postgresql.install: true and postgresql.auth.sslmode: disable in your values.
