我有运行 Ruby 1.9.2、Rails 3 和 postgreSQL 8.3 的应用程序。它最初是在 postgreSQL 9.1 上设置和工作的，但我卸载了 9.1 并安装并更改为 8.3，以确保在 Heroku 共享数据库设置上的兼容性。运行正常，但现在不行

现在，在使用此应用程序时，当我运行数据库升级时，我收到此错误：

dlopen(/Users/michaeljmccoy/.rvm/gems/ruby-1.9.2-p290/gems/pg-0.12.2/lib/pg_ext.bundle, 9): Library not loaded: libpq.5.dylib

当我尝试运行服务器时，我收到以下错误消息：

我知道它们是非常相似的错误，可能与缺少路径有关。但是，当我将路径添加到我的 .profile 文件并重新启动终端窗口时，我得到了同样的错误。

您可能需要删除并重新安装pggem，因此它是针对正确版本的 Postgres 编译的。

对于看到此错误并运行 PostgresApp 的任何人，这是一个已在 9.2.4.3 版中修复的已知问题：

讨论：https ://github.com/PostgresApp/PostgresApp/issues/109

安装程序：https ://github.com/PostgresApp/PostgresApp/releases/tag/9.2.4.3

当然，您可以获取最新版本（http://postgresapp.com/）。这两个版本都让我恢复并运行 Rails 3.2.14 和 Ruby 2.0.0。但是，请注意，当我安装 9.2.4.3 时，我的数据库仍然在 psql 中列出，但是当我安装 9.3.0（目前的当前版本）时，我的数据库不再列出。
