Hello Vijaykumar!
Thank you for your useful links. I've just installed
prometheus-community/postgres_exporter and it is working. It is
also useful that it comes with a ready Grafana dashboard. I've installed
Grafana dashboard "9628" and found it not very useful (in comparison
e.g. with the standard Zabbix PostgreSQL template), but maybe I've not
invested enough time studying it.
I have not looked at the alerter yet.
