It works fine. But it terminates only one PID due to LIMIT 1. I want to terminate all pids that meet this criteria. If I remove LIMIT 1, pg_terminate_backend(pid)
will not work as it expects only one pid at a time. So, the question is how to rewrite this psql so it loops through all pids one pid at a time? Thanks in advance for your help. > > SELECT pid, pg_terminate_backend(pid) FROM pg_stat_activity > WHERE pid IN (select unnest(pg_blocking_pids(pid)) from pg_stat_activity where cardinality(pg_blocking_pids(pid)) > 0) > and usename = 'DBUSER_10' > and now() - state_change >= interval $a'${TIMEOUT_MINS}'$a > order by now() - state_change >= interval $a'${TIMEOUT_MINS}'$a desc limit 1; Did you try? I don't see any reason why it wouldn't work with just 'limit 1' removed. Best regards, depesz Thanks, depesz. I am pretty sure removing “limit 1” should terminate all pids in the result set. I was just being dumb. |
