Remove `pg_stat_monitor`¶

To uninstall pg_stat_monitor, do the following:

Disable statistics collection. Establish the psql session and run the following command :
```
ALTER SYSTEM SET pg_stat_monitor.track = none;
```
Drop pg_stat_monitor extension:
```
DROP EXTENSION pg_stat_monitor;
```
Remove pg_stat_monitor from the shared_preload_libraries configuration parameter:
```
ALTER SYSTEM SET shared_preload_libraries = '';
```
Important

If the shared_preload_libraries parameter includes other modules, specify them all for the ALTER SYSTEM SET command to keep using them.
Restart the postgresql instance to apply the changes. The following command restarts PostgreSQL 15. Replace the version value with the one you are using.
- On Debian and Ubuntu:
```
$ sudo systemctl restart postgresql.service
```
- On Red Hat Enterprise Linux and CentOS:
```
$ sudo systemctl restart postgresql-15
```
