Who the heck approved the attached for pgsql-announce?
There was another item on -announce recently that should never have been approved (http://archives.postgresql.org/pgsql-announce/2012-12/msg00016.php) ... maybe something is broken about the mailing list logic that's supposed to prevent unapproved messages from going through?
I asked the same question on -slavestothewww but didn't get any response.
