datasource我有一个名为 jsonb 列的postgresql 表data。它具有以下结构：

{  
   "key1":{"param1" : "value1", "param2" : "value2"},
   "key2":{"param2_1" : "value2_1", "param2_2" : "value2_2"},
   "key3":{"param3_1" : "value3_1", "param3_2" : "value3_2"}  
}

有没有办法编写一些 UPDATE 脚本来将给定的 JSON 转换为以下内容：

[  
   {"key": "key1", "param1" : "value1", "param2" : "value2"},
   {"key": "key2", "param2_1" : "value2_1", "param2_2" : "value2_2"},
   {"key": "key3", "param3_1" : "value3_1", "param3_2" : "value3_2"}  
]
