Suggested change

	Displays control information of a PostgreSQL database cluster.
	The system utility `pg_controldata` displays the control information of an Apache Cloudberry cluster.

To improve the readability.

Suggested change

	Only the user who initialized the cluster and has read access to the data directory can run the utility. The access restriction ensures the integrity and security of the sensitive control information.

| `-PG_COLOR` | Determine whether to use color in diagnostic messages. The available values are `always`, `auto` and `never`. Setting the value to `always` ensures that diagnostic messages are always presented in color, which enhances readability and visual identification of important information. Setting the value to `auto` enables color-coding based on the capabilities of the output terminal.Setting the value to `never` disables the usage of color entirely. |

	| `-PG_COLOR` | 该变量决定是否在诊断消息中使用颜色。可用值有 `always（始终）`, `auto（自动）` 和 `never（从不）`。将值设置为 `always（始终）` 可确保诊断消息始终以彩色显示，这样可以提高可读性并从视觉上识别重要信息。将值设置为 `auto（自动）` 可根据输出终端的功能进行颜色编码。将值设置为 `never（从不）`则完全禁用颜色。 |
