我迷路了 您的会话日志告诉服务器是作为先决条件安装的，但“链接”消息暗示已经存在不兼容的客户端版本。可能您已经从CentOS软件包中安装了PostgreSQL，但是pglogical RPM将PGDG软件包引入 错误消息可能意味着
shared\u preload\u库pglogicalpglogical。因此在lib
目录中找不到
安装过程可能在旧服务器安装中编辑了配置，但在新服务器安装中安装了共享对象
结果：您不能在安装中使用这些逻辑二进制文件。切换到PGDG RPM或从源生成PGDG逻辑
您可以看到，我的推论中有一定数量的推测，但这应该可以帮助您解决问题。show log\u destination给我stderr
。我尝试指定日志位置：pg_ctl start-D/var/lib/pgsql/data/-l pg.log
，它创建了pg.log文件，它有完全相同的错误：FATAL:无法访问文件“pglogical”：没有这样的文件或目录
日志：数据库系统已关闭
我也运行了initdb。这没用。
