我已成功将我的ruby版本从1.9.3升级到2.0.0。
升级后，我运行以下命令：
heroku run "ruby -v"
我得到了以下结果：
ruby 2.0.0p451 (2014-02-24 revision 45167) [x86_64-linux]
所以它说它已成功升级。
但是我的服务器在升级后会停止运行。
我正在粘贴我的日志：

我相信这是关注的重点。

要解决此问题，请确保初始化程序和/或DATABASE_URL环境变量没有错误地将字符串（查询参数）连接到结尾，例如？mode = test＆amp; ssl_cert =？pool = 25。
我有一个DATABASE_URL，在heroku配置中添加了查询参数，但在我正在附加的sidekiq工作者的初始化程序中添加了'？pool = 5'的附加参数。在以前的版本中，这似乎正确解析，或者更有可能只是降低了价值。
更改我的DATABASE_URL以正确链接查询params与领先？然后＆amp;加入params数据库连接成功。
