Hi Essobi,

the distribution with the hash index was introduced to support load balancing. 
If you partition your database according this hash index, then its not 
possible to simply go to another target.

If you want failover, just go in the failure_route in the script to the next 
domain. Then you should have something like "weighted failover groups". Look 
in the example in the documentation:

Cheers,
