我们目前有一个托管在pg 13.1（与PostGIS 3.1.1）的数据库，我们渴望转移到pg 15.3（与PostGIS 3.3.3），所有运行在Windows 10上。
我安装了pg15没有问题。pgAdmin 4实用程序（与postgres 15捆绑）连接正常。
然后，我使用pg_tagde.exe实用程序成功地将我们的数据库迁移到新的pg15服务器。

pg_upgrade.exe --old-datadir "D:\PostgreSQL\13\data" --new-datadir "D:\PostgreSQL\15\data" --old-bindir "C:\Program Files\PostgreSQL\13\bin" --new-bindir "C:\Program Files\PostgreSQL\15\bin" --username=super_user

字符串
我们的应用程序和服务似乎对新的pg15数据库很满意。
然而，使用pg_tagde.exe实用程序迁移我们的数据库导致了某种问题，pgAdmin（与15捆绑的版本）将不再访问我们的服务器。
启动较新的pgAdmin会导致UI出现超时错误，并在pgAdmin日志文件中出现以下错误

我已经安装了最新的pgAdmin4（v7.6），但这给出了相同的错误。
