PG :: UndefinedFile：错误：无法打开扩展控制文件

升级Postgres后，我收到以下错误，当我尝试迁移数据库。PG :: UndefinedFile：错误：无法打开扩展控制文件

不确定从哪里开始。大多数其他问题似乎与Linux相关，当我尝试创建符号链接时，它也无法工作。

您是否尝试过'brew install postgis'？ – max

看起来像PostGIS需要重新安装，是的。出于某种原因，Homebrew似乎会安装到包含次要版本（如/9.4.5/）的目录中，这会在每次较小的更新时破坏内容。 –

您应该安装postgresql-9.4-postgis-2.1
