pg_stat_activity is not real time, and should not be because its
intended use is to help interpret the also-not-real-time other
statistics.
If people are concerned about this, my inclination would be to add a
separate view, or just add even more columns to pg_locks?
However, all you could get from ProcArray would be the database in
which the backend is running, and maybe the owning user's ID if we
cared to expend the extra space to store it there. We're certainly
not going to add current_query or any such thing into that array.
