Hi 2016-09-27 23:03 GMT+02:00 Mike Sofen <mso...@runbox.com <mailto:mso...@runbox.com> >: Hi gang, how to view the state of a transaction in flight, seeing how many rows have been read or inserted (possible for a transaction in flight?), memory allocations across the various PG processes, etc. some years ago I used a trick http://okbob.blogspot.cz/2014/09/nice-unix-filter-pv.html#links pltoolbox has counter function https://github.com/okbob/pltoolbox/blob/master/utils.c pavel=# insert into omega2 select (x.xx).* from (select pst.counter(omega,200000, true) xx from omega ) x; NOTICE: processed 200000 rows, current value is '(5,8)' NOTICE: processed 200000 rows, current value is '(5,8)' Regards Pavel Pavel - That’s a very interesting function and thanks for sharing your toolbox. The big question of course, is what is the impact on performance, scalability and stability? Would it work inside of a stored function that would allow me write out the progress to a tracking table?
