delete storage group root.group; 出错

root 用户 删除存储组错误
msg:401error occurred while parsing sql to physical plan:1:26 mismatched input 'group' expecting {'*','**',STRING.ID,QUTOED_ID_IN_NODE_NAME}
使用 show storage group; 可查询到

Reproduce the reported error by querying `show storage group;` and attempting to delete `root.group`, then trace the SQL parsing and physical-plan error. Done means the valid storage-group deletion no longer fails because `group` is parsed incorrectly, with coverage for this command if the project has an applicable test location.
