title: PGSQL driver not found in Laravel PHP Framework
body: <p>Hi I am using Laravel PHP framework on CentOS 6.3. I have PostgreSQL 9.1 installed, along with PDO and PDO-PGSQL. Under <code>application/config/database.php</code> I have set Laravel to use PostgreSQL:</p>
  
  <pre><code>'default' =&gt; 'pgsql',
  
  
  'connections' =&gt; array(
  
      'pgsql' =&gt; array(
          'driver'   =&gt; 'pgsql',
          'host'     =&gt; 'localhost',
          'database' =&gt; 'dbname',
          'username' =&gt; 'username',
          'password' =&gt; 'shhhpass',
          'charset'  =&gt; 'utf8',
          'prefix'   =&gt; '',
          'schema'   =&gt; 'public',
      ),
  ),
  </code></pre>
  
  <p>However, visiting any page gives me the error: </p>
  
  <pre><code>Message:
  
  could not find driver
  Location:     
  
  /home/dev/public_html/laravel/database/connectors/postgres.php on line 37
  </code></pre>
  
  <p>Any ideas? Thanks!</p>
