If you're superuser you can delete rows all you want. You could
probably cons up something that deletes rows with PIDs not found in
the pg_stat_activity view.
I'm more interested in how the rows got there though. The bugs I was
thinking of were surely stomped long before 7.3.4, so if you're not
suffering crashes then you must have found a new one. Please keep an
eye on it and see if you can figure out the circumstances in which a row
gets left behind. Since you know the PIDs of the delinquent backends,
maybe you could look at the last related entries in the postmaster log
(turn on log_pid if you're not using syslog for logging).
