I'd like to request that selected parts of the user table be included in the dumps for statisticical purposes, namely the user_id, user_name and user_options fields.
does mysqldump have support for dumping only certain columns?
And before people get all up in arms about this then no, this does not include your email or the hash of your password (those are in user_email and user_password respectively).
i have no particular opinion, but i suspect some people would object to preferences being included in dumps.
