This almost sounds like it takes the year 2000, figures out it needs 366
days, and uses that for "1 year".

However, I don't see that error myself:

template1=> select '2000-12-31'::timestamp+'1 year';
?column?
------------------------
2001-12-31 00:00:00-08
(1 row)

template1=> select '2000-12-31'::timestamp+'1 year'::timespan;
?column?
------------------------
2001-12-31 00:00:00-08
(1 row)
