 We recommend upgrading your PostgreSQL user database servers to version 7.3.4 for better performance. 
               NOTE:The upgrade is made only for PostgreSQL user database servers! 
               It WILL NOT upgrade the system PostgreSQL on the Control Panel server!
 
              Log into your control panel server as root:
 
                su -
                Unpack the archive:
 
                tar -zxf u-pgsql.tgz
                Enter the unpacked directory:
 
                cd u-pgsql
                To upgrade all PostgreSQL user database servers, run the update.sh script:
 
                sh update.shand you're done. Alternatively, to upgrade PostgreSQL only on a particular box, copy the pgupdt.tgz archive
                from the u-pgsql to that server, untar that archive, and run sh pgupdate.sh 
                in the untarred pgupdate directory.
