Is psqlha-postgresql-ha-postgresql-2
displayed on the Instances
tab?
Can you also check the Coroot's log for errors?
Replication roles are currently discovered only for clusters managed by the k8s operators for Postgres (Zalando, CrunchyData, Percona).

Yep, it's displayed on instances tab. All three are green on the instances tab, now psqlha-postgresql-ha-postgresql-1 is not recognised as a postgres service.
I do see new errors in logs, namely:
couldn't find actual instance for "postgres", initial instance is "10.1.18.172:80" (map[])
and that ip (18.172) does belong to pod psqlha-postgresql-ha-postgresql-1
from coroot.
Please show the output of the following Prometheus queries:
container_net_tcp_listen_info{listen_addr="10.1.18.172:80"}
container_net_tcp_listen_info{container_id=~".*psqlha-postgresql-ha-postgresql-1.*"}
from coroot.
Both metrics were empty. I also noticed that they were simply wrong for most IP addresses - showing ports that could never exist in a pod. Restarted daemonset, now those metrics seem valid. Waiting for 10 minutes to let coroot settle.
No noticeable errors were found in node-agent logs prior to restarting the daemonset.
P.S. psqlha-postgresql-ha-postgresql-1 was deployed on a node which had it's network connectivity abruptly cut off recently. Then it was rebooted without restoring networking first. Could help in narrowing it down, i guess...
