It would be very unusual to have an expense from a customer, and we do
not have (yet) a name for supplier or whatever it should be here, so i
used the same name we use for the column in the table.
I had to change MethodOverrider to check whether the form is encoded as
multipart/form-data or i would not be able to get the method field from
forms with files.
For now i add the file manually, i.e., outside add_expense and
edit_expense PL/pgSQL functions, because it was faster for me, but i
will probably add an attach_to_expense function, or something like that,
to avoid having the whole ON CONFLICT logic inside Golang—this belongs
to the database.
