Are you using PgJDBC or the extended query protocol? This reminds me of this thread: https://www.postgresql.org/message-id/flat/CA%2B427g8qBArPuqwZOuYVhdoCQUsdbutR18fG7Gt7%2B3JunuHsjA%40mail.gmail.com That was about pg_stat_activity, though. But the key take-away was that query_id is not computed in the extended query protocol which is used by PgJDBC. -- Erik
