使用datax迁移pgsql数据如何配置能使同步重复的主键id不报错

使用网上介绍的再writer的preSql中配置insert into target_table(id,data) values(?,?) on conflict(id) do nothing;会报错：
经DataX智能分析,该任务最可能的错误原因是:
com.alibaba.datax.common.exception.DataXException: Code:[DBUtilErrorCode-06], Description:[执行数据库 Sql 失败, 请检查您的配置的 column/table/where/querySql或者向 DBA 寻求帮助.]. - 执行的SQL为: insert into target_table(id,data) values(?,?) on conflict(id) do nothing; 具体错误信息为：org.postgresql.util.PSQLException: 错误: 语法错误 在 "," 或附近的
请问如何能使datax同步pgsql重复的主键id时不报错？

Start with the DataX writer preSql configuration shown in the issue and trace how it is executed against PostgreSQL. Reproduce the reported syntax error with the target_table statement, then verify a supported configuration or behavior that completes synchronization when duplicate primary-key ids are encountered without an error.
