[pgpool-general: 8228] load_balance_mode is off by default but balancing works?

[Nikola(HM)]

Hello,

For our Pgpool, we did not set the parameter load_balance_mode. Its 
default is off. When we noticed this, we checked it by command "pgpool 
show load_balance_mode". Check returned 0. This means balancing was 
disabled. Correctly?

However, the load balancing worked, according to various checks (for 
example, "show pool_nodes" command), read requests were routed to 
read-only replicas.

Could you comment on this behavior of Pgpool?

Thanks in advance.
