title: Adding PostgreSQL support to already installed PHP
body: <p>I have php-5.3.6 and postgresql installed in my Fedora 13. But it seems that postgresql support is not enabled in php. My phpinfo() page doesn't show any PostgreSQL section, neither pdo_pgsql section.</p>
  
  <p>I checked /etc/php.ini, and it shows that PostgresSQL is enabled.</p>
  
  <pre><code>[root@localhost ~]# cat /etc/php.ini | grep ^pgsql
  pgsql.allow_persistent = On
  pgsql.auto_reset_persistent = Off
  pgsql.max_persistent = -1
  pgsql.max_links = -1
  pgsql.ignore_notice = 0
  pgsql.log_notice = 0
  </code></pre>
  
  <p>Is there any way I can add postgresql support to php without recompiling it from the source? Is there any other files I need to make some changes?</p>
