Any idea why? As I wrote in my previous message, pg_catalog.pg_db_role_setting will tell you if compute_query_id is set for any user/database combination which overrides the system-wide default from postgresql.conf for new sessions. Your query results don't include usernames and databases. I assume the JDBC connections are with a different user or on a different database than the psql and pgwatch2 connections for which query_id is calculated. Could be that postgresql.conf sets compute_query_id=off and only the users that you used for psql and pgwatch2 have compute_query_id={on,auto}. Then there's also the chance that the applications using the JDBC driver set compute_query_id=off before sending queries. Doesn't explain however why this would also be the case for that one connection from IntelliJ IDEA (which I assume uses JDBC as well). I doubt that JDBC sets compute_query_id=off by default. My guess is user-specific session defaults. -- Erik
