Mysteries of the future

Description:

I'm not sure that there will be 31 days in 11 months; although postgresql
probably knows better what will happen in 20000 

For example (with the year 20000): to_date('200001131', 'YYYYMMDD') will be
interpreted as a 4-digit year; instead use a non-digit separator after the
year, like to_date('20000-1131', 'YYYY-MMDD') or to_date('20000Nov31',
'YYYYMonDD').

```sql
SELECT to_date('20000-1131', 'YYYY-MMDD');

ERROR:  22008: date/time field value out of range: "20000-1131"
LOCATION:  DateTimeParseError, datetime.c:4021
