2、修改Mapper文件

2.1、 涉及分页的sql修改

LIMIT #{offset}, #{pagesize}
修改为：
LIMIT #{pagesize} offset #{offset}

---

LIMIT 0, #{limit}
修改为：
LIMIT #{limit}

2.2、非运算符替换

全局搜索：findFailJobLogIds，将！替换为 not

2.3、时间转换函数修改

XxlJobRegistryMapper.xml文件
全局搜索（两处修改）：WHERE t.update_time DATE_ADD(#{nowTime},INTERVAL -#{timeout} SECOND)
替换为：WHERE t.update_time ((select NOW()) -INTERVAL ‘${timeout} S’)

2.4、as语句替换

pgsql的as语句不加双引号会变成全小写，造成xxl-job首页数据异常。
XxlJobLogMapper.xml文件findLogReport方法的triggerDayCount，triggerDayCountRunning，triggerDayCountSuc都加上英文双引号。

3、修改properties配置文件

数据库配置修改为pgsql

### xxl-job, datasource
spring.datasource.url=jdbc:postgresql://127.0.0.1:5432/test
spring.datasource.username=postgres
spring.datasource.password=123456
spring.datasource.driver-class-name=org.postgresql.Driver

4、pom文件修改

增加pgsql的依赖

	org.postgresql
	postgresql
	42.4.0
