[pgpool-hackers: 4419] [Question] : If pgpool-2 is illustrated in different DC & DR nodes and if SUBNETS are also different, Is this architecture supported?

Hi Everyone ,

Need One Help for a new PGPOOL Customer Env setup. Please guide me...
Details of the Architecture as below:

1 :- Customer having DC & DR Setup
2 :- Customer wants to place PGPOOL services in both nodes.
3 :- Following is Architecture Details

DC [ called as PROD ]:-

Standby     10.8.77.215          UP
Primary     10.8.77.216          UP
Witness     10.8.77.217          N/A --- PGPOOL-II

DR:-

Standby     10.68.1.174          UP
Standby     10.68.1.175          UP
Witness     10.68.1.176          N/A --- PGPOOL II

4 :- DC having IP Range 10.8
5 :- DR having IP Range 10.68

Now the pending point here is "Delegate IP".

If the Customer is going to add "Delegate IP" from DC -10.8 subnet and
if in case PGPOOL-II node Fails from the DC side and then PGPOOL-II
taking command for load balancing.
However here Delegate IP range is 10.8 but DR side subnet ranging 10.68.
Is this Delegate IP transfer using if_up_cmd & if_down_cmd where the
subnet is different.
1 :- Is this architecture supported? Where PGPOOL services are
situated in different DC & DR and subnets are also different.
2 :- If Yes, then how can Delegate IP be treated here ?

Thanks & Regards
