It's not v$pq_stat, but v$pq_tqstat, like
select dfo_number, tq_id, server_type, process, num_rows, bytes, avg_latency, waits, timeouts from v$pq_tqstat
order by 1, 2, 3, 4, 5
Anyway, with additional infos like execution plan, code template and v $pq_tqstat result, we would bave better discussions.
