Site admin is succesfully converted from SQLite to PostgreSQL.

(For future reference, here are the steps I took:)

1. Installed the ar fixures plugin
2. Created a list of my models with a shell script
3. Iterated over the models calling Model.dump_to_file
4. Changed database config from sqlite to postgresql
5. rake db:migrate
6. Iterated over the models calling Model.load_from_file
