Description

我遇到一个使用纯钧获取 postgresql 中的空间类型数据 遇到了数据类型不能转换的问题.

1. 转换string,会报错java.lang.ClassCastException: org.postgresql.util.PGobject cannot be cast to java.lang.String

chunjun是怎么做 空间数据类型 的 转换呢

chunJun目前不支持这种类型做转换，如果你有好的想法，可以贡献给chunjun

@FlechazoW 若某库没有这种空间类型，这个要怎么存储 ？把空间数据变成字符串去存储？这样可以接受不？

用字符串的格式存储能快速转换吗？用binary 存储会不会更好呢？
