I added the following one:

+local function upgrade_to_2_3_1_1()
+    -- Formats must be equal in order to avoid crashes in SQL
+    -- caused by incorrectly allocated cursor.
+    local _func = box.space[box.schema.FUNC_ID]
+    local _vfunc = box.space[box.schema.VFUNC_ID]
+    _vfunc:format(_func:format())
+end
+
