title: I've unintentionally created a production database. Will this destroy the production data that already exists?
body: <p>Context:
  I've built a rails app that's in production. Originally, the scope of the project was small so I didn't need to write tests, but as it grows, it's now imperative that I have them.</p>
  
  <p>As I set up rspec along with the test database, I ran the following command: </p>
  
  <pre><code>`rake db:create:all`
  </code></pre>
  
  <p>I received the following response:</p>
  
  <pre><code>Database 'db/development.sqlite3' already exists
  Database 'db/test.sqlite3' already exists
  Created database 'db/production.sqlite3'`
  </code></pre>
  
  <p>Question:
  Given the fact that I have a deployed application (on Heroku) with a production database that's already up and running, is that final line (
  <code>Created database 'db/production.sqlite3</code>) going to destroy any data once I merge my changes and push my code up to production?</p>
  
  <p>Further, since I'm already using a different database in production, should I delete it? If so, how?</p>
  
  <p>I would be happy to add any details that someone would need in order to give a helpful response! Thanks in advance</p>
