Hi. I have a transaction running at the database for around 20 hours .. still isn't done. But during the last hours it has come to the point where it really hurts performance of "other queries". Given pg_stat_activity output there seems to be no locks interfering but the overall cpu-usage of all queries continue to rise. iowait numbers are also very low. What can I do to make the system handle other queries better?
