Postgres 使用条件组子查询将行合并到一个数组中

Question

SELECT json_object(array_agg(product_store), array_agg(json::text))as price_log FROM (
SELECT product_store, array_agg(array["Logs".product_price::text, "Logs".last_updated::text]) as json
                     FROM "Logs"
                     WHERE "Logs".product_id = 13
                     GROUP BY "Logs".product_store
) as price_log

输出

也许我以错误的方式解决这个问题，我正在尝试组合与产品 ID 关联的“日志”行，因为这是在子查询中使用的，我需要将此查询放在一个数组中，因为有多次出现多个结果，如上。

我想要的结果是：

{
"BestBuy.com":{
 "Data:{
 "24.99,\"2023-04-08 00:20:13.756603+00\",
 "24.99,\"2023-04-08 00:20:13.756603+00\"
 }
},
"Target":{
  "Data": {
   "24.99,\"2023-04-08 00:20:13.756603+00\",
   "24.99,\"2023-04-08 00:20:13.756603+00\"
  }
}
}
