PG :: UndefinedFile：錯誤：無法打開擴展控制文件

升級Postgres後，我收到以下錯誤，當我嘗試遷移數據庫。PG :: UndefinedFile：錯誤：無法打開擴展控制文件

不確定從哪裏開始。大多數其他問題似乎與Linux相關，當我嘗試創建符號鏈接時，它也無法工作。

您是否嘗試過'brew install postgis'？ – max

看起來像PostGIS需要重新安裝，是的。出於某種原因，Homebrew似乎會安裝到包含次要版本（如/9.4.5/）的目錄中，這會在每次較小的更新時破壞內容。 –

您應該安裝postgresql-9.4-postgis-2.1

只需將[it]（https://github.com/Casecommons/pg_search/issues/38）放在這裏。 – Netsu
