Mailing lists archive missing mail?

hi,
I was trying to find this email:

>> To: pgsql-committers@postgresql.org
>> Subject: [COMMITTERS] pgsql: Reduce lock levels of CREATE TRIGGER and some ALTER TABLE, CREATE
>> Message-Id: <20100728052224.C50817541D5@cvs.postgresql.org>
>> Date: Wed, 28 Jul 2010 05:22:24 +0000 (UTC)
>> From: Simon Riggs <sriggs@postgresql.org>
>> X-Mailing-List: pgsql-committers

in archives ( http://archives.postgresql.org/pgsql-committers/2010-07/index.php )
but it's not there.
Why?

Best regards,

depesz
