We run docker image pgpool/pgpool:4.2.2 in Kubernetes.

I found that

- if I set load_balance_mode off,  load balancing doesn't work

- if I remove load_balance_mode parameter from environment variables 
list, assuming  the default value of load_balance_mode, load balancing 
works! And 'pgpool SHOW load_balance_mode' command returns 'on'.
