// l1.time_id AS currev_time, l2.time_id AS oldrev_time
// FROM logs AS l1
// LEFT JOIN logs AS l2
// ON ( l1.log_type = l2.log_type AND l1.action = 'edit' AND l1.action = l2.action AND l2.time_id < l1.time_id AND l1.page_id = l2.page_id AND l1.namespace = l2.namespace )

// GROUP BY l1.page_id, l1.namespace
// ORDER BY l2.time_id DESC, l1.time_id DESC;
// (the actual query is generated based on filter criteria)
// How it works:
// * Join the logs table with itself
// * Select the size_change virtual column, which is based on current_rev_length - old_rev_length
// * Use GROUP BY to group rows from the same page together
// * Make sure that the time_id in the second instance (l2) of enano_logs is LESS than the time_id in the first instance (l1)
// * Use ORDER BY to ensure that the latest revision before current is selected
