PROMPT3 当执行COPY命令，并期望在终端输入数据时（例如，COPY FROM STDIN），显示提示符。 使用变量PROMPT3显示COPY提示符： openGauss=# \set PROMPT3 '>>>>' openGauss=# copy HR.areaS from STDIN;来自：专题关于COPY FROM STDIN导入数据 这种方式适合数据写入量不太大， 并发度不太高的场景。 用户可以使用以下方式通过COPY FROM STDIN语句直接向 GaussDB (DWS)写入数据。 通过键盘输入向GaussDB(DWS)写入数据。 通过JDBC驱动的CopyMan来自：帮助中心
