据我所知，Amazon RDS支持停止和启动数据库实例。 我正在从Mac OS Sierra运行该实例 我想使用AWS命令行界面（遵循本教程：http://docs.aws.amazon.com/cli/latest/reference/rds/start-db-instance.html）
启动数据库实例但不知怎的，我收到了一个错误：
MacBook-Pro-de-lopes:~ lopes$ aws rds start-db-instance lopesdbtest
usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:
aws help
aws <command> help
aws <command> <subcommand> help

Invalid choice: 'start-db-instance', maybe you meant:
* reboot-db-instance
* create-db-instance

您需要更新到最新版本的AWS CLI工具。您当前安装的版本是在RDS启动/停止功能可用之前发布的。

这是一项新功能（于2017年6月1日公布）。您必须升级AWS CLI。
