I don't have a strong opinion on the whitespace handling, but then I wonder
1. If I put four YYYY, why does it create a six-digit year?
2. If it does create a six digit year, the rest of the pattern doesn't match
anymore, so it should error.
A further example shows that to_date seems to have little error checking
altogether:
select to_date('17.12.1978', 'YYYY-MM-DD'); to_date
------------0017-12-19
That can't possibly be a good idea, in the interest of the robustness of
applications built on this.
select to_date('whatever', 'foobar'); to_date
---------------0001-01-01 BC
Yah.
