Self-node check method not changed.

[Rayjun0525]

Even if the connection_check_type setting in repmgr is changed to query, the self-check method is still performed using PQping.
Is there a way to change all connection check methods to a method other than query or PQping?

Can't someone give me a solution to this problem?
