[pgpool-hackers: 2046] Pgpool-II should not perform ping test after bringing down the VIP

[Muhammad Usama]

Hi

At the time de-escalation from the master watchdog node, Pgpool-II should
not perform the ping test to verify if the VIP is successfully brought down
or not.

The reason is, if the newly elected master watchdog node acquires the VIP
while the resigning Pgpool-II node is still performing the de-escalation
steps or doing the ping test on VIP. The resigning Pgpool-II will
falsely assume that it has failed to bring down the delegate IP, after
getting the positive ping result from the new master node that has already
acquired that VIP.

Comments and suggestions are welcome.

Kind regards
Muhammad Usama
