自遷移到postgresql數據庫後登錄後出現堆棧SQL錯誤？

這是一個非常奇怪的錯誤胸圍基本上我只是將我的應用程序從sqlite3移動到PostgreSQL。我使用devise ruby gem來處理用戶的會話管理。我正在使用rails 3.1.0.rc4和Devise 1.4.2。無論如何，嘗試登錄會產生這個錯誤：自遷移到postgresql數據庫後登錄後出現堆棧SQL錯誤？

這是一個ActiveRecord的bug或東西嗎？

問題是由我試圖急於負荷團隊與用戶造成的事實：

class User < ActiveRecord::Base 
    has_many :teams 
    default_scope :include => :teams 
end

Issue is on Github now。應該在下一個Rails RC中修復。

您可以添加關於db/schema.rb中的模式db關於表的問題信息：用戶，成員和團隊嗎？
