Capistrano, beta deployment and different database?


I’ve modified my deploy.rb to deploy a beta version of my site (trunk, rather than a tag) if I supply the BETA environment variable. It uses a different mongrel config and a different deploy_to. I’d also like to use a seperate MySQL database, yet as far as I know, we’re stuck with the test, development and production databases. I don’t want development mode (don’t want the reloads) so something like appname_beta_production would be good. Any idea how I can stay in production mode but override the database?
