Re: empty,query_id, pg_stat_activity

If the query_id* is null, it is not actually running yet. This is a good
thing as far as your stated tracking requirements. You can do a WHERE
query_id IS NOT NULL to exclude statements where the query has appeared,
but has not been parsed and executed yet. I daresay you also want to be
looking at wait_event and now()-state_change as well.

Cheers,
Greg


* Actually, query_id some places, queryid in others. So annoying.
