title: Could not find driver pdo_pgsql symfony 2.8
body: <p>I made a lot of search and didn't find any solution.
  Whenever I try to php app/console doctrine:database:create, SF2 returns me an error "could not find driver".</p>
  
  <p>I went in /app/config.php and configured my php.ini correctly.
  Extensions are uncommented and enabled.</p>
  
  <p>php -m tells me pgsql is activated.
  phpinfo(); too, and also tells me the path of the bin which's used. (which is the one noticed on /web/config.php).</p>
  
  <p>I tried all I could, but i can't create a database. </p>
  
  <p>Any help would be appreciated.</p>
  
  <pre><code>doctrine:
  dbal:
      driver:   pdo_pgsql
      host:     "%database_host%"
      port:     "%database_port%"
      dbname:   "%database_name%"
      user:     "%database_user%"
      password: "%database_password%"
      charset:  UTF8
  
  
  extension=pgsql.so
  extension=pdo_pgsql.so (in php.ini)
  </code></pre>
  
  <p>I don't know ... </p>
