Ruby on rails 使用2台postgres服务器转储数据库时出错

我在ubuntu版本上安装了2台postgres服务器：9.3.6；版本：9.2.6。如何定义在rails中使用哪个pg_转储版本

  $ rake db:migrate
  pg_dump: server version: 9.3.6; pg_dump version: 9.2.6
  pg_dump: aborting because of server version mismatch
  rake aborted!

我的解决方案是：在迁移到所需postgres bin dir之前定义

PATH

变量

export PATH="/usr/lib/postgresql/9.3/bin/:$PATH"
rake db:migrate
