This query will show you the pid, client_addr and user that submitted the
queries, in addition to other useful information.

SELECT backend_start as be_start,
       datname,
       pid as pid,
       client_addr,
       usename as user,
       state,
       query,
       wait_event_type,
       query_start,
       current_timestamp - query_start as duration
  FROM pg_stat_activity
 WHERE pg_backend_pid() <> pid
ORDER BY 1,
         datname,
         query_start;
