您如何更新https://artifacthub.io上主要 postgresql 图表的 postgresql.conf 或 pg_hba.conf ？（特别是我一直在尝试更新 postgresql.conf 中的 wal_level）

如果没有任何真正好的例子，文档很难遵循，但基本上在细则中他们提到如果你想在这里更新任何东西，你必须完全覆盖 postgresql.conf 和 pg_hba.conf。我确信有一种更好的方法可以只更新一个键，例如 wal_level，但我发现这种方法目前是最好的。
将此 yaml 复制到文件 (/path/to/this/file/values_bitnami_pg_postgresql_conf.yaml) 中，并在安装图表时使用 if。这个 yaml 包含我在撰写本文时发现可以编辑的所有键。
