1、测试环境导出一张表：

e053000@Cameroon:~> pg_dump -f cfg_public_special_service.sql -U cpost -t cfg_public_special_service -a --inserts

2、开发环境备份该表：

zhanghuijun@Africa:~/zhj> pg_dump -f cfg_public_special_service_20131022.sql -t cfg_public_special_service -a --inserts

备份后清空该表：truncate

3、windows导入：

把该文件传到windows机器，使用大象（pgAdmin）执行语句，由于字符集问题出错；

----not OK

4、linux导入：

把该文件传到开发机（linux）：

zhanghuijun@Africa:~/zhj> psql -f cfg_public_special_service.sql

----OK
