Hello Jeremy,
thanks for your input (and sorry for the delay).
for our monitoring we query like this
SELECT EXTRACT(epoch FROM (LOCALTIMESTAMP -
pg_stat_activity.query_start))::integer AS age
FROM pg_stat_activity
WHERE pg_stat_activity.state = 'active' AND query NOT LIKE 'autovacuum:%'
ORDER BY pg_stat_activity.query_start ASC
LIMIT 1
but we stumble over the query nontheless, its state being active
+---------+---------------------------------------------------------+
| Zustand | Laufende Abfrage |
+---------+---------------------------------------------------------+
| active | SELECT pg_catalog.set_config('search_path', '', false); |
+---------+---------------------------------------------------------+
is there another good way to exclude it?
regards
Hannes

We found out because we are monitoring long running queries, and
saw it had been running for a month before the restart yesterday.
I just queried pg_stat_activity and it seems to be running since
then.
taimusz=# SELECT pid, query_start, usename, left(query,70)
FROM pg_stat_activity
WHERE query != '<IDLE>' AND query NOT ILIKE '%pg_stat_activity%'
ORDER BY query_start;
pid | query_start | usename
| left

You should add: AND state != 'idle' to filter out queries that are no
longer running and don't have an open transaction. Your query is
finding long running sessions, not necessarily long running queries.
