Hi, I have postgresql 11. And I want to create an entegration PMM.
Pmm Client version is : Version: 2.36.0

I connected to Pmm Server with below code

pmm-admin config --force --server-insecure-tls --server-url=https://admin:admin@server_ip

And I create a super user in postgresql for pmm
Then I try to add service like below code. It says yes service added successfully

`pmm-admin add postgresql --username=‘pmm_user’ --password=‘pass’

PostgreSQL Service added.
Service ID : /service_id/7a44a924-b
Service name: Node1-postgresql

But When I check ‘/var/log/postgresql/postgresql11.log’ It gives below error message for every 1 minute.

function pg_stat_monitor_version() does not exist at character 38

Set up - pg_stat_monitor Documentation (percona.com) should help.
