title: I cannot install pdo_pgsql.so to use PostgreSQL in PHP
body: <p>I have a site that use PostgreSQL database but I found that my RHEL 5 system lacks of pdo_pgsql.so file. I have spent several hours trying to install it but it was impossible.</p>
  
  <p>When using "rpm -i" command with a lot RPMs found in Internet, I always got dependencies problems.</p>
  
  <p>Last command I have issued before posting here was:</p>
  
  <p>rpm -i <a href="http://yum.postgresql.org/9.1/redhat/rhel-5-i386/pgdg-redhat91-9.1-5.noarch.rpm" rel="nofollow">http://yum.postgresql.org/9.1/redhat/rhel-5-i386/pgdg-redhat91-9.1-5.noarch.rpm</a></p>
  
  <p>The output to that command was: package pgdg-redhat91-9.1-5 is already installed</p>
  
  <p>And in fact, PostgreSQL database is up and running. The only missing file is pdo_pgsql.so.</p>
  
  <p>I have used "find . / -name pdo_pgsql.so" to see if that file is somewhere in the disk, but without success.</p>
  
  <p>Can you point me to the right direction, please?</p>
  
  <p>These are relevant versions:</p>
  
  <ul>
  <li>psql (PostgreSQL) 9.1.2</li>
  <li>PHP 5.3.27 (cli) (built: Dec  8 2013 19:01:03) </li>
  <li>Server version: Apache/2.4.1 (Unix)</li>
  <li>Red Hat Enterprise Linux Server release 5 (Tikanga)</li>
  </ul>
  
  <p>Cheers
