Posted this message on Core, but maybe it belongs here.

The subject pretty much says it all. I’m getting ready to set up an  
environment for working on my first patch, and I discovered that the  
activerecord/test/schema files have changed, but the Rakefile hasn’t  
yet been updated.

Is there a simple way to set up the test databases with the new  
system?
