 * Kinda of gross operations to change the pilot ID column
 * 1. Add an `pilot_id` column, which will get populated with the current ID
 * 2. Drop the `id` column, and then recreate it as a string field
 * 3. Iterate through all of the users and set their `id` to the `pilot_id`
 * 4. Change the other tables column types that reference `user_id`
