How to change bitnami postgresql helm chart configs? (ph_hba.conf, postgresql.conf)

Question

How do you update postgresql.conf or pg_hba.conf for the main postgresql chart on https://artifacthub.io? (In particular I have been trying to update the wal_level within the postgresql.conf)

Answer 1

Using values.yaml with the following content

primary:
  extendedConfiguration: |-
    wal_level = logical

you can easily override only the wal_level

helm install my-postgresql bitnami/postgresql -f values.yaml
