Re: BUG #18348: Inconsistency with EXTRACT([field] from INTERVAL);

in `9.9.1. EXTRACT, date_part`
EXTRACT(field FROM source)

I saw more inconsistencies with the doc when `source` is an interval.

the `minute` field
select extract(minute from interval '2011 year 16 month 35 day 48 hour
1005 min 71 sec 11 ms');
select extract(minute from interval '2011 year 16 month 35 day 48 hour
1005 min 2 sec 11 ms');
select extract(minute from interval '2011 year 16 month 35 day 48 hour
1005 min 2 sec 11 ms');

the `hour` field:
select extract(hour from interval '2011 year 16 month 35 day 48 hour
1005 min 71 sec 11 ms');
select extract(hour from interval '2011 year 16 month 35 day 48 hour
1005 min 2 sec 11 ms');
select extract(hour from interval '2011 year 16 month 35 day 48 hour
1005 min 71 sec 11111111111 ms');

the `quarter` field:
select extract(quarter from interval '2011 year 12 month 48 hour 1005
min 2 sec 11 ms');
SELECT EXTRACT(QUARTER FROM TIMESTAMP '2001-12-16 20:38:40');
