Well maybe phpMyAdmin doesn't offer gzip compression for SQL, but still it does offer Open Document download, for which gzip-compression is needed.
It doesn't work now and will confuse customers.
My main Apache PHP-module has gz and bz support.
I think the switch Norman supposed is a good thing, it will enhance phpMyAdmin for most people.
If I want to update my ISPconfig to 2.2.9, how should I do it to enable gzip/bz support in phpmyadmin.
