Please don't follow the directions on that ca 2004 blog page.  Google 
should be publicly shamed for telling people where to find those old, 
incorrect directions--that can result in a corrupt database.  Seems the 
guy who made the page does have a /very/ good understanding of one 
thing, though--search engine optimization.  (Not that that would be any 
use to someone trying to set up a new system as their master backend.)

The wiki page you quoted is good--and shows the process you should 
follow.  Specifically the part about doing a complete restore of a 
/complete/ database backup (not the partial backup that blog post says 
to do) and changing the host name/IP address in the database if you used 
a different host name and/or IP address for your new system.
