A client has several production queries that commonly run an hour or two.
Sometimes queries are modified infelicitously or the planner is lead astray
due to statistics etc and they can run much longer unexpectedly. It would be
useful to set a threshold of a few hours to catch those as reproducing them
is a slow process.
