MySQL query to set all feeds to disable auto-generation of terms & a few other questions

Hi,

Thanks for this new feature. I have about 500 feeds, so disabling that for each feed will take me some time. Is there a mysql query I can use to disable all of them at once? I know it's in aggregation_feed_options, but I can't find it, and don't quite get how these combined-options-in-single-text-strings work.

Also, after upgrading from 4.3 to 4.4 on Drupal 5.10, the dropdown under "Aggregation feed types: *" in settings is empty.
