DataX抽取Postgresql uuid字段类型报错

报错描述如下：

- 您的配置文件中的列配置信息有误. 因为DataX 不支持数据库读取这种字段类型. 字段名:[AId], 字段名称:[1111], 字段Java类型:[java.util.UUID]. 请尝试使用数据库函数将其转换datax支持的类型 或者不同步该字段 .

解决方案：
使用PG的显示类型转换 `::text`

Start by reproducing the reported DataX PostgreSQL extraction failure with a UUID column and compare it with the documented ::text cast workaround. Trace how the UUID value becomes java.util.UUID and identify the relevant PostgreSQL reader entry point. Done means UUID columns are handled appropriately without requiring the workaround, with coverage for the reported case.
