我正在使用mybatis将数据插入postgresql数据库。我有19629条记录要插入。我试图一次插入所有记录。但如果我向查询传递超过6k条记录，我将得到原因：org.postgresql.util.PSQLException:发送到后端时发生I/O错误。
那么在postgresql中一次插入记录的数量有限制吗？

Mybatis代码。

{ @Insert({ "<script>","insert into temp_overdrive_csv_dtls (lpat_library_card_number,day_of_use,sessions,minutes_read,hours_read,sys_created_by)","values ", "<foreach  collection='recordList' item='record' separator=','>","(#{record.lpatLibraryCardNumber},#{record.dayofUse}, #{record.sessions}, #{record.minutesRead}, #{record.hoursRead}, #{record.sysCreatedBy})","</foreach>", "</script>" })public Integer insert(@Param("recordList") List<CsvRecord> recordList);

错误。

Error updating database.  Cause: org.postgresql.util.PSQLException: An I/O error occurred while sending to the backend.

该错误可能涉及com. apds. mybatis. mapper. overdrive. overdriveTotMapper.插入-内联
设置参数SQL时出错：插入到临时超速驱动csv dtl（磁带库卡号，使用日，会话，分钟读取，小时读取，系统创建人）值（？，？，？，？，？，？），（？，？，？，？，？，？），（？，？，？，？，？，？），（？，？，？，？，？，？），（？，？，？，？，？，？，？），，，（？，？，？，？，？，？）

原因：组织。postgresql。实用程序。PSQLException：发送到后端时发生I/O错误。
