pg_dump服务器版本不匹配

Question

每当我在Rails应用程序的数据库上运行rake任务时,我都会收到以下错误.

pg_dump: server version: 9.2.4; pg_dump version: 9.1.5
pg_dump: aborting because of server version mismatch

我已经用Google搜索了一下,并找到了一些关于更新postgres brew包的建议,但这没有用.

为什么使用了错误的pg_dump版本,我该如何解决这个问题？或者我应该寻找哪些搜索条件来寻找解决方案？

关于我的pg_dump配置的信息:

$ pg_dump --version
> pg_dump (PostgreSQL) 9.1.5
$ which pg_dump
> /usr/bin/pg_dump
$ echo $PATH
> /Users/andrewharvey/.rvm/gems/ruby-1.9.3-p392@mantawatch/bin:/Users/andrewharvey/.rvm/gems/ruby-1.9.3-p392@global/bin:/Users/andrewharvey/.rvm/rubies/ruby-1.9.3-p392/bin:/Users/andrewharvey/.rvm/bin:/usr/local/heroku/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/andrewharvey/.rvm/bin

我正在使用oh_my_zsh,并且路径是在我的.zshrc文件中定义的.这可能是我的问题的原因(我确信这可以清理),不幸的是我不知道我正在做什么来调试和编辑它.感谢指针(我正在使用通过Homebrew安装的RVM和postgres).

source $ZSH/oh-my-zsh.sh

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

alias pg='pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log'

export
 PATH=$PATH:/usr/local/bin:/Users/andrewharvey/.rvm/gems/ruby-2.0.0-p0/bin:/Users/andrewharvey/.rvm/gems/ruby-2.0.0-p0@global/bin:/Users/andrewharvey/.rvm/rubies/ruby-2.0.0-p0/bin:/Users/andrewharvey/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

对于mac用户放在.profile文件的顶部.

export PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"

然后运行

. ~/.profile
