Ignoring unknown application_name/node

[RajasekarArumugam28]

Hi Team, I have recently upgraded the node to Postgres 15 and I could see the below INFO in pacemaker log. I have verified in barman side and found no issues there and how to stop this Info message and why am I getting this.

tail -f pacemaker.log
pgsqlms(pgsqld)[3729375]: May 01 09:56:56 INFO: Ignoring unknown application_name/node "barman_receive_wal"

Hi,

Yes, this is expected if you have something else replicating from the primary that is not a known node from pacemaker perspective. Issue #178 exists about these flooding messages. I'm not sure how to deal with them though.

If you have some idea about how to deal with that, do not hesitate to discuss them in #178.

Thanks,
