查看 percona server for mongodb 的版本

安装 percona server for mongodb 后，使用mongosh登录，并不能看到关于percona版本的对应信息。比如：

# mongosh
Current Mongosh Log ID: 67c6a0e7eac840351494d971
Connecting to:          mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+2.3.2
Using MongoDB:          7.0.16-10
Using Mongosh:          2.3.2
mongosh 2.4.0 is available for download: https://www.mongodb.com/try/download/shell

For mongosh info see: https://www.mongodb.com/docs/mongodb-shell/

Warning: Found ~/.mongorc.js, but not ~/.mongoshrc.js. ~/.mongorc.js will not be loaded.
  You may want to copy or rename ~/.mongorc.js to ~/.mongoshrc.js.

可以借助 buildInfo 命令来查看对应的 percona server for mongodb 版本信息。输出结果中，查看关键字 psmdbVersion 的信息即可。如果没有 psmdbVersion 关键字，表示不是 percona 版本。

> db.runCommand( { buildInfo: 1 } )
