[development] DB trivia - fun for everyone!

The db schema documentation patch (http://drupal.org/node/164983) is quite close to being completed but we still have a small list of unknowns. If folks that are familiar with these could give us some descriptions, I'm more than willing to roll them into the patch. FIELDS: aggregator_category.block aggregator_feed.image aggregator_feed.etag aggregator_feed.block aggregator_item.guid search_index.fromsid search_index.fromtype IN SYSTEM.SCHEMA: cache - table flood - table menu_links - table files.status - field system.owner - field This would be awesome to have in Drupal 6 but we need to get it knocked out soon. Thanks! - Addi
