The above query will get you a list of PIDs that are accessing the db.
At the command line, as user postgres, do a kill -2 on those PIDs. DO
NOT kill -9 them.
If you don't find any entries in the pg_stat_activity table, then it may
be the case that you're not monitoring it. In that case, again as user
postgres, do a ps xww to find connections and then kill them as
described previously.
All of the above assumes that you're running on a unix platform.
