Dear Percona team

As per our Infosec team, Postgres 16.8 is not vulnerable and needs to be upgraded in all our Production servers however, we are having frequent crashes due to pg\_stat\_monitor version 2.1.0 which was reported earlier. We had tried installing 2.0 however still issue persist. Without pg\_stat\_monitor we cannot use QAN in PMM hence this is becoming a show stopper for implementing in our prod environments. Kindly provide a permanent solution for this.

@Mohan

Did you try with latest pg\_stat\_monitor v2.2 ? It should support fine with PG 16. Let us know if you still facing the issues.

```auto
bash-4.4$ psql
psql (16.7)
Type "help" for help.

```

```auto
postgres=# \dx pg_stat_monitor

> Install pg\_stat\_monitor

Moreover, are there any particular queries or operations where the crash usually triggers or it happens randomly ? Do you have the postgres error logs for a review ?

As far as QAN is concerned you can also rely on **pg\_stat\_statements** - [PostgreSQL - Percona Monitoring and Management](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/install-pmm-client/connect-database/postgresql.html#configure-monitoring-extension)
