In commit 472d14179 (Beaker 0.6.14) I updated model.py to make recipe.recipe_set_id and recipe_set.job_id not NULLable, but I neglected to add schema upgrade notes to effect the same change. So any old Beaker databases (including our production database) will not have this change. The fix will just be a schema upgrade note.
