Interesting this argument comes from you.. :-)

Tasks like purging old log files is certainly not a job that needs to be
implemented in the backend; instead, an external database maintenance
agent should do that.
Such an agent (pgadmin TODO list working title: pgAgent, there was a
lengthy discussion "Scheduled jobs" starting 2004-05-12), allowing
scheduled sql scripts, would delete old log files using

select pg_file_unlink(filename)
   from pg_logdir_ls
  where filetime < now() - '8 days'::interval

*if* this functionality isn't corrupted by arbitrary selectable file
name formatting.
