select age(now(),pg_stat_activity.query_start) as "age", pg_stat_activity.datname, pg_stat_activity.usename, pg_stat_activity.client_addr, pg_stat_activity.application_name, pg_locks.transactionid, pg_locks.transaction, pg_stat_activity.procpid, pg_stat_activity.query_start, pg_locks.mode, pg_stat_activity.current_query from pg_stat_activity, pg_locks where pg_locks.pid = pg_stat_activity.procpid and procpid <> pg_backend_pid() and pg_locks.transactionid = pg_locks.transaction order by 1 desc; |
