It appears this bug has made a come back with PostgreSQL 14.3. 
The query that appears is the following :

```
select pid, usename, client_addr, client_hostname, wait_event_type, wait_event_type || ':' || wait_event as wait_event, query, datname, application_name, backend_type, query_id from pg_stat_activity w where w.state = 'active' and COALESCE(w.wait_event,'') not in ('WalSenderMain','WalSenderWaitForWAL');

```

Can you confirm this is purely a Performance Insight bug and could you look into a fix ?

Thanks a lot !
