In 8.2 or later it should do so; in prior versions there could be some
lag involved. Another thing to keep in mind is that backends like to
cache copies of the pg_stat_activity view --- if you are watching it
to see what is happening, your view is only current as of the start
of your current transaction. Or you can do pgstat_clear_snapshot()
to force collection of new info.
