我正在MySql数据库上运行Heroku应用程序。
现在我想切换到PostgreSql是有原因的,为此我更改了database.yml,并根据PostgreSql的要求更改了迁移文件。
我还更改了同一应用程序的数据库URL和共享数据库URL。
但当我去申请的时候,它就崩溃了。
显示以下错误的日志

我希望在切换Heroku的数据库时遵循步骤,或者如何避免上述错误。
编辑:-
我的.gems文件如下
rails -v 2.3.8
spreadsheet --version 0.6.4
spreadsheet-excel --version 0.3.5.1
rack --version 1.1.0
money --version 2.2.0
fastercsv --version 1.5.3
xml-mapping --version 0.8.1
当我更改'rack--version 1.1.0'ot'rack--version 1.0.0'
当做,
