to_date's absymal lack of error checking is well known. It should
surely refuse that input altogether, given that format string.
Feel free to send a patch ...

As for the range issue, date_in does refuse negative Julian dates:

regression=# select '4714-01-27 BC'::date;
ERROR: date out of range: "4714-01-27 BC"

but again to_date doesn't:

regression=# select to_date('4714-01-27 BC', 'YYYY-MM-DD BC');
to_date
---------------
4714-01-27 BC
(1 row)
