在 Windows 上安装 PostgreSQL

官网下载地址：

https://www.enterprisedb.com/downloads/postgres-postgresql-downloads

Windows平台

官网直接提供exe安装包，没有手动安装的压缩包

postgresql-14.4-1-windows-x64.exe

几个重要的安装选项

• 安装界面会指定服务程序和库两个路径，可以自己手动选择

• 指定默认账户的密码

• 选择额外的安装项（这里我选了一个JDBC驱动包，方便DBeaver访问）

记录一下

上述安装完成之后，使用navicat进行连接访问，发现身份验证失败：

修改办法：

使用navicat进行连接访问，发现乱码：

参考这篇文章，发现是配置在DB目录的配置

升级Navicat版本至16.2.5总算正常了！！
