PostGIS在Heroku上无法正常工作

Question

将postGIS添加到heroku数据库并检查它是否已安装。但它不承认rgeo和postgis方法。 我的坐标是:geometry类型。本地都很好，但生产WKT格式无法识别。

实施例： 在开发回报中：

"POINT (45.815927 16.00538)"

在生产回报中：

0101000000581CCEFC6AE8464003E962D34A013040

错误我在尝试访问/api/v1/elements/index时遇到了错误：

The page you were looking for doesn't exist (404)
