> If we run the following script:
> drop table if exists t;
>  create table t (c1 interval year to month, c2 interval month);
>  insert into t values (interval '11-01' year to month, interval '11' month);
> select DATE_PART('YEARQUARTER', c1) from t;
>  select DATE_PART('YEARQUARTER', c2) from t;
> select DATE_PART('YEARMONTH', c1) from t;
>  select DATE_PART('YEARMONTH', c2) from t;
> select DATE_PART('YEARWEEK', c1) from t;
>  select DATE_PART('YEARWEEK', c2) from t;
> We get correct 4037 error messages on column c2. For YEARQUARTER and YEARMONTH on c1 though we get an internal error 8001 at run-time instead. For YEARWEEK we get a compile time error 4035 on c1 instead.
