+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`.
