Sorry. DB is Aurora Postgres 14.6. Hints are enabled via extension pg_hint_plan. But my question isn't so much about
thehints but the execution plan and where the time is going and why it appears for 1 execution of the query skipping
lockedrows seems to take a lot more time than another execution of the query.
