Rails database.yml question when using Amazon RDS

How should my database.yml production look like when I am using Heroku and Amazon RDS?

My database.yml

# SQLite version 3.x
# gem install sqlite3-ruby (not necessary on OS X Leopard)
# gem 'mysql', '2.8.1'

    development:
      adapter: mysql
      database: konkurranceportalen
      encoding: utf8
      pool: 5
      username: root
      password: 
      socket: C:/xampp/mysql/bin/mysqld.sock
      host: 127.0.0.1

    # Warning: The database defined as 开发者_开发知识库"test" will be erased and
    # re-generated from your development database when you run "rake".
    # Do not set this db to the same as development or production.

    test:
      adapter: mysql
      database: rails_t
      encoding: utf8
      pool: 5
      username: root
      password: 
      socket: C:/xampp/mysql/bin/mysqld.sock
      host: 127.0.0.1

    production:
      adapter: mysql
      database: rails_t
      encoding: utf8
      pool: 5
      username: root
      password: 
      socket: C:/xampp/mysql/bin/mysqld.sock
      host: 127.0.0.1
