现象：

使用注解@GlobalTransactional 就会抛异常，无法插入数据

若使用@transactional 则不会抛异常，正常插入数据

解决思路：

1. 排查自己的postgresql依赖版本

推荐使用

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>42.3.3</version>
</dependency>

2. 升级druid依赖

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.2.16</version>
</dependency>

综合考虑后放弃使用seata
