The current documentation notes/suggestions regarding `pg_stat_monitor` are a bit confusing to newcomers. See https://www.percona.com/doc/percona-monitoring-and-management/2.x/setting-up/client/postgresql/index.html
Perhaps placing the information related to pg_stat_monitor in a separate box/paragraph instead of peppering it over the PG summary would help bring clarity to it.
These are the notes I shared with someone who was confused about it:
- pg_stat_monitor, a new extension created by Percona, based on pg_stat_statements and compatible with it.
- pg_stat_monitor is in beta, and we don't yet offer support for it.
- If you decide to try it out, at your own risk, you will need to disable pg_stat_statements because running both at the same time will result in duplicate metrics
