org.postgresql.util.PSQLException: 不支援 10 验证类型

场景：本来想在工作项目上整合工作流 flowable，一直没成功，就在本地安装了 postgre，想在本地先看看能不能成功，pom 文件是复制工作项目的配置，启动后一直报这个错误：

org.postgresql.util.PSQLException: 不支援 10 验证类型。请核对您已经组态 pg_hba.conf 文件包含客户端的IP位址或网路区段，以及驱动程序所支援的验证架构模式已被支援。

这个问题是因为，postgre 的驱动版本比较老，我使用的是这个版本：

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>9.4.1212.jre7</version>
</dependency>

但是我本地安装的 postgre 版本是 14

后面我切换成这个版本的驱动，就没问题了

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>42.5.0</version>
</dependency>

不过这个异常的场景不止这个。
