But it evidently *isn't* checked. As of CVS tip:
regression=# select to_timestamp('44 October 2003', 'DD FMMonth YYYY');
to_timestamp
------------------------
2003-11-13 00:00:00-05
(1 row)
The regular timestamp input converter certainly has the checks:
regression=# select '44 October 2003'::timestamp;
ERROR: invalid input syntax for type timestamp: "44 October 2003"
but evidently those checks are not in whatever code path to_timestamp
is calling.
