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;
