我在尝试保存已格式化为 GeoJSON 的多边形时遇到问题，问题是我将多边形作为坐标数组数组，但 postgres 多边形字段需要一个元组数组，但 javascript 没有支持元组，因此我不知道如何将数据插入 Postgres。

postgres 如何获取数据的示例：

INSERT INTO table VALUES(default, '[(x,y), (x,y)]');

我拥有的数据示例：

"coordinates": [
          [
            [
              49.5703125,
              59.5343180010956
            ],
            [
              54.84375,
              54.77534585936447
            ],
            [
              63.28125,
              59.5343180010956
            ],
            [
              54.84375,
              61.77312286453146
            ],
            [
              49.5703125,
              60.930432202923335
            ],
            [
              49.5703125,
              59.5343180010956
            ]
          ]
        ]

尝试将数组保存到 postgres 时遇到的错误：
