Hello everyone.

We have a pgpool & postgres setup made as per the given example 

We haven't configured the if_up_cmd, if_down_cmd & arping_cmd in pgpool.conf (we commented it out on purpose). We enabled the delegate_ip and assigned a unused IP.

While we bringing up the pgpool the log shows VIP is successfully UP via if_up_cmd, how is this happening? any default way is considering the if_up_cmd to bring the VIP?

2024-06-18 08:27:02.735: watchdog_utility pid 102493: LOG:  successfully acquired the delegate IP:"10.127.1.20"
2024-06-18 08:27:02.735: watchdog_utility pid 102493: DETAIL:  'if_up_cmd' returned with success
2024-06-18 08:27:02.735: watchdog pid 102378: LOG:  watchdog escalation process with pid: 102493 exit with SUCCESS.

NOTE: We run into some situation so that we disabled the if_* commands in the configuration and started pgpool, but VIP is getting acquired by the leader pgpool node even the if_* commands are not used in pgpool.conf file.

Can anyone explain how the VIP works in pgpool watchdog

Thank you
