We recommend upgrading your PostgreSQL user database servers to version 7.3.4 for better performance.

1. Log into your control panel server as root:
   
   su -
2. Unpack the archive:
   
   tar -zxf u-pgsql.tgz
3. Enter the unpacked directory:
   
   cd u-pgsql
4. To upgrade all PostgreSQL user database servers, run the update.sh script:
   
   sh update.sh
   and 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.
