Rails database backup & restore plugin or rake task


Searching in internet finds me mysql specific things and outdated rake
tasks. I want a portable one. So using postgresql database, I want to
dump my db data into a file. Then I want to load the file into mysql

Any one know where I can find one?

Nevermind. I find it. http://blog.leetsoft.com/2006/5/29/easy-migration-between-databases
