[TRAFODION-3043] Add missing binder check for DATE_PART function
This change adds a check to Extract::synthesizeType

DATE_PART on an Interval data type with an extract qualifier of YEARMONTH or
YEARQUARTER.

> URL: https://issues.apache.org/jira/browse/TRAFODION-3043
> Project: Apache Trafodion
> Issue Type: Bug
> Components: sql-cmp
> Affects Versions: 2.3
> Reporter: David Wayne Birdsall
> Assignee: David Wayne Birdsall
> Priority: Major
>
> 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.
