Where is the summary of interactive docs' comments? - Mailing list pgsql-www

In previous release cycles it was helpful to use
http://www.postgresql.org/idocs/checknotes.php
to look at all the comments that had been entered on the interactive
documentation pages.

But now I can't get to it :-(.  The URL seems to get redirected to
http://www.postgresql.org/docs/checknotes.php
(not "idocs") which may or may not be the problem.

Anyone know if that page is still available?  If so, where?

            regards, tom lane
