使用PostgreSQL加載模式之後的Rails語法錯誤

我遇到了問題，我無法理解在其他地方找到解決方案。事情是，當我試圖加載架構與使用PostgreSQL加載模式之後的Rails語法錯誤

load "#{Rails.root}/db/sctructure.sql"

錯誤出現。 postgresql版本是9.5.1，pg gem是0.8.1。正如我所能理解的，pg gem無法識別轉儲文件的註釋。你有沒有遇到類似的東西？

您看到這個錯誤，因爲你無法load SQL文件。 load僅用於加載紅寶石文件。

有沒有什麼辦法可以在我的模型中加載db/structure.sql文件？ – marinoszak

您是否嘗試過'rake db：schema：load'？ –

我已經嘗試過，但我認爲db：schema：load不加載structure.sql文件。它僅適用於schema.rb，還是我錯了？在我寫的應用程序中，我有多個租戶，當我創建新租戶時，我想更改search_path並加載structure.sql文件。 – marinoszak
