使用ActiveRecord和Rails将数据插入postgresql数据库会出现此错误：RuntimeError：ERROR C22003 Minteger o
我正在使用Ruby 1.8.6和rails 2.1.1（我也测试了rails 2.2.2）。 我一直在使用Sqlite3，我最近迁移到Postgresql 8.2.6进行生产使用。 现在出现此错误。 有趣的是，当我复制插入语句并使用psql直接将其插入postgres时它工作正常。 我想问题是在轨道级别的某个地方。 但是，我不知道它是什么。 所以，如果有人知道问题是什么或如何解决它，请告诉我。

错误发生在PostgreSQL级别。 错误22003是PostgreSQL的“数字值超出范围”错误，如此处所示。 快速浏览一下insert语句会显示大于32位的整数，这些整数可能就是罪魁祸首。
