Hello Tatsuo,
I realized that only a small subset of values can be changed, and also this
change will be session-local.
I did not see it initially (in documentation for PGPOOL_SET page), but
section 5.1 (
https://www.pgpool.net/docs/43/en/html/config-setting.html#CONFIG-SETTING-SQL-COMMAND-INTERACTION)
states it clearly.
So, i dont think there is a problem!
Thanks for your help,
Michail
