title: How do I put PostgreSQL /bin directory on my path in Windows?
body: <p>I've got a fairly simple question I guess. I'm working on a Ruby on Rails app.
  I'm trying to switch to PostgreSQL thanks to Heroku.</p>
  
  <p>In my database.yml file it states:</p>
  
  <blockquote>
  <pre><code>  Install PostgreSQL and put its /bin directory on your path.
  </code></pre>
  </blockquote>
  
  <p>My question is how do I put PostgreSQL's /bin directory on my path? Exactly which file do I modify and how?</p>
  
  <p>I imagine this is my issue since when I run the "rails db" command i get:</p>
  
  <p>"Couldn't find database client: psql,psql.exe. Check your $PATH and try again."</p>
  
  <p>Thanks everyone!
  Robin.</p>
