hi. for all the progress report views[1], we can add a timestamptz column, maybe named as query_start.
People generally want to track the progress of operations and the time spent on them. While pg_stat_activity already provides column query_start, including query_start in pg_stat_get_progress_info would eliminate the need for JOIN with pg_stat_activity in some cases. Overall it will make the progress report monitoring more convenient, IMHO. as of implementation: we can occupy pg_stat_get_progress_info last parameter param20 for column query_start. what do you think?
