title: Rails database setup on Travis-CI
body: <p>I'm trying to use Travis Continuous Integration on a Rails project. The documentation says that the test db must be configured as following for SQLite3:</p>
  
  <pre><code>test:
    adapter: sqlite3
    database: ":memory:"
    timeout: 500
  </code></pre>
  
  <p>But I'd like to keep my default configuration for local tests. Is it possible to keep both my local settings and the Travis requirements?</p>
