charts/postgresql/files/README.md

+Copy here your postgresql.conf and/or pg_hba.conf files to use it as a config map.

charts/postgresql/files/conf.d/README.md

+If you don't want to provide the whole configuration file and only specify certain parameters, you can copy here your extended `.conf` files.
+These files will be injected as a config maps and add/overwrite the default configuration using the `include_dir` directive that allows settings to be loaded from files other than the default `postgresql.conf`.
+
+More info in the [bitnami-docker-postgresql README](https://github.com/bitnami/bitnami-docker-postgresql#configuration-file).

charts/postgresql/files/docker-entrypoint-initdb.d/README.md

+You can copy here your custom `.sh`, `.sql` or `.sql.gz` file so they are executed during the first boot of the image.
