It is rejected by the standard date input converter:
regression=# select '2005-02-32'::date;
ERROR: date/time field value out of range: "2005-02-32"
HINT: Perhaps you need a different "datestyle" setting.
However we consider that to_date() exists to be Oracle compatible,
and so I would regard this as a bug if and only if Oracle does
something different with the same input. Anyone know?
