Is the bug system active?

Is the bug system at:

    http://www.ca.postgresql.org/bugs/

actively in use? I recently reported the following bug:

    http://www.ca.postgresql.org/bugs/bugs.php?4~415

and after doing so browsed through a number of earlier bugs it appears
that the vast majority are still 'unassigned' and not evaluated after
a long period of time (like over a year)! Surely if this system is
being ignored it should be removed from the website...

Thanks, Lee Kindness.
