There's no special config for this specific error message. It is logged as
FATAL so the only way to silence it *and any other messages from DEBUG5 to FATAL*
is to set log_min_messages = PANIC. I don't recommend it. It also complicates
troubleshooting failing connections in the future if you don't log this message.
When logging to syslog you may be able to discard specific messages.
rsyslog has property-based filters[0] for example:
:msg, contains, "pg_hba.conf rejects connection for host" ~
You should also investigate the clients that try connecting ("a lot" as you
write) and figure out why they keep connecting if you want to reject their
attempts anyway.
