Please, consider this small fix for the query example in the docs[1]:
SELECT a.pid, a.wait_event, w.description
FROM pg_stat_activity a JOIN
pg_wait_events w ON (a.wait_event_type = w.type AND
a.wait_event = w.name)
WHERE wait_event is NOT NULL and a.state = 'active';
I propose to add a table alias for the wait_event column in the WHERE clause for consistency.
