“ pg_dump：无效选项-我”迁移时 [英] "pg_dump: invalid option -- i" when migrating
问题描述
当我在Rails项目（3.2.22.2）上运行 rake db：migrate 时，我得到 pg_dump：无效的选项-i 。完整的跟踪记录如下：
When I run rake db:migrate on my Rails project (3.2.22.2) I get pg_dump: invalid option -- i. Here's the full trace:

我注意到有一个 Rails中的错误修正与此问题有关。该错误修复程序似乎尚未应用于Rails版本< 4，因为它不是安全修复程序，很有意义。
I notice that there's a bugfix in Rails pertaining to this issue. The bugfix seems not to have been applied to Rails versions < 4 since it's not a security fix, which makes sense.
我不明白的是我现在应该做什么。如果存在针对3.2.x的修复程序，我还无法找到它。我想如果没有针对3.2.x的修复程序，我想那意味着我必须升级到Rails 4.x，这似乎有些过激。我怀疑这真的是唯一的解决方案。为什么最近才突然出现这个问题呢？
What I don't understand is what I'm supposed to do now. If there's a fix for 3.2.x, I haven't been able to find it yet. I guess if there's no fix for 3.2.x, I guess that means I have to upgrade to Rails 4.x, which seems a bit drastic. I doubt that's really the only solution. And why did the issue only recently pop up out of nowhere?
任何建议都会受到赞赏。
Any suggestions are appreciated.
推荐答案
不太可能有修复程序，因为它不是安全问题。即使是这样，我也不确定他们是否正在修补3.x。
Unlikely there is a fix as it's not a security issue. Even if it was, I'm not sure they are patching 3.x anymore.
问题出在这里的db：structure：dump任务中：
The problem is in the db:structure:dump task here:
最简单的方法是复制该任务（413-448）并将其放入到您自己的lib / tasks目录中，在其周围包装一个 namespace db ，调整pg_dump命令（删除-i），您的任务应覆盖内置任务。
Easiest thing is to copy that task (413 - 448) and put it into your own lib/tasks directory, wrap a namespace db around it, tweak the pg_dump command (remove -i) and your task should override the built in task.
