If your aim is avoiding duplication in your YAML file, not necessarily including external file, I recommend doing something like this:

development: &default
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: db_dev
  pool: 5
  username: usr
  password: psw
  host: localhost
  port: 3306

dev_cache:
  <<: *default

new:
  <<: *default
  database: db_new

test:
  <<: *default
  database: db_test
