When the sql backend creates an INSERT or UPDATE statement, it gets a
list of GValues, one for each field.  It then needs to convert them to
ascii.  For this, it uses g_value_transform() if the GType is
transformable to G_TYPE_STRING.  If the GType is not transformable, I
want something in the log identifying the type, and I was using "%d" and
the GType value.  I can switch to the GType name.
