我的应用程序运行的是Ruby1.9.2、Rails3和postgreSQL 8.3。它最初是安装在Heroku9.1上的，但我卸载了9.1，然后安装并更改为8.3，以确保在postgreSQL共享数据库设置上的兼容性。它以前运行正常，但现在不是这样
现在，在使用此应用程序时，当我运行数据库升级时，我收到以下错误：
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

from script/rails:6:in `<main>'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.profile文件并重新启动终端窗口时，我得到了相同的错误。

您可能需要删除并重新安装Postgres，以便在正确版本的pg上编译它。

对于看到此错误并运行PostgresApp的任何人，这是一个已知问题，已在版本9.2.4.3中修复：
讨论：https://github.com/PostgresApp/PostgresApp/issues/109
安装者：https://github.com/PostgresApp/PostgresApp/releases/tag/9.2.4.3
当然，您可以只获取最新版本(http://postgresapp.com/)。这两个版本都让我重新使用Rails 3.2.14和Ruby 2.0.0。但是，请注意，当我安装9.2.4.3时，我的数据库仍然列在psql中，但是当我安装9.3.0 (当前版本)时，我的数据库不再列出。
