Hello Guys,
I have case of two Postgres version 11 ( replication using repmgr) and and its work fine as below:
-bash-4.2$ sudo su - postgres -c " /usr/pgsql-11/bin/repmgr -f /var/lib/pgsql/repmgr/repmgr.conf cluster show"
ID | Name | Role | Status | Upstream | Location | Priority | Connection string
----+-------+---------+-----------+----------+----------+----------+--------------------------------------
1 | pgdb1 | standby | running | pgdb2 | default | 100 | host=pgdb1 user=repmgr dbname=repmgr
2 | pgdb2 | primary | * running | | default | 100 | host=pgdb2 user=repmgr dbname=repmgr

2 | pgdb2 | primary | * running | | default | 100 | host=pgdb2 user=repmgr dbname=repmgr
but when I installed pgpool 4.1 on third server to loadbalace the traffic ., from command line I see everything ok like below:
-bash-4.2$ psql -U pgpool --dbname=postgres --host pgpool -c "show pool_nodes"
node_id | hostname | port | status | lb_weight | role | select_cnt | load_balance_node | replication_delay | replication_state | replication_sync_state | last_statu
