Cpanel failurls File
The failurls file, located at /var/cpanel/failurls, allows you to specify where resellers can redirect users who fail to authenticate with cPanel.
Enter the URLs to which resellers can redirect users, one per line, in the file.
Entries in this file must meet the following requirements:
Entries must be an exact match. Dynamic URLs are not acceptable.
Example:
http://example.com/index.php?failed=1
Dynamic content on the login page must be passed via hidden POST variables. Using the GET query string will fail because it will not match any entry in the failurls file exactly. When you are finished creating entries in the failurls file, you must restart cPanel. To restart cPanel, run the following command as the root user:
/usr/local/cpanel/startup
Reference : http://cpanel.net/

Installing PostgreSQL on Your cPanel/WHM Server

Move your existing PostgreSQL data directory somewhere else by, for example, typing the following command:
mv /var/lib/pgsql /var/lib/pgsql.old
Type the following command:
From WHM now select Postgres Config in the SQL Services section of WHM. Type a new PostgreSQL password in the text box and click Change Password.
