PostgreSQL: Allow BC dates like datetime consistently

BC dates are supported by both date and datetime types.

https://www.postgresql.org/docs/current/static/datatype-datetime.html

Since #1097, new datetime allows year zero as 1 BC, but new date does
not. It should be allowed even in new date consistently.
