I have test it with postgresql 17.7
I have been searching on postgresql src for commits related with client_connection_check_interval, and I only see initial commits in postgresql 14, I think it happends in all versions from 14 until 18, but I can only confirm on 17.7

Regards,
Alfonso Escribano

Hello,
I have seen an interaction between "client_connection_check_interval" and "log_lock_waits" parameters that it isn't documented (or I can't find it anywhere).

What version of Postgres?

Regards,
Alfonso Escribano
