> {{SqlDatePartFunction#rewriteCall}} does not check operands length for now,
> and it will be rewrite to {{EXTRACT}} unconditionally before validation.
> E.g.
> {code:sql}
> select week(); -- will throw ArrayIndexOutOfBoundsException
> select week(date '2022-04-27', 1); -- will just ignore second param
> {code}
> However, these cases should throw validation exceptions, because {{week}}
> actually only accept 1 operand.
