If you have two PF machines (One for each ADSL) you can use CARP to get the 
failover you require. 



Otherwise failover between to WANs on the same Pf machine is covered in the 
load balancing.

Do you have dual router setup or are those WAN's connected to the same 
machine? If you have dual router setup, then WAN failover won't work for 
you. I have tested it extensively with no luck of any combination. 
Single machile dual WAN failover works.
