  <p>I'm trying to get Redmine working with postgres.</p>
  
  <p>In my logs I keep seeing.</p>
  
  <pre><code>Please install the postgresql adapter: `gem install activerecord-postgresql-adapter`
  </code></pre>
  
  <p>After googling everyone said you needed to do gem install pg.  But when I do gem list</p>
  
  <pre><code>actionmailer (2.3.5)
  actionpack (2.3.5)
  activerecord (2.3.8, 2.3.5)
  activeresource (2.3.5)
  activesupport (2.3.8, 2.3.5)
  fastthread (1.0.7)
  passenger (2.2.15)
  pg (0.9.0)
  postgres (0.7.9.2008.01.28)
  postgres-pr (0.6.3)
  rack (1.0.1)
  rails (2.3.5)
  rake (0.8.7)
  </code></pre>
  
  <p>You can clearly see that pg is already installed.  Has anyone else found this issue or fixed it?</p>
