I came across an unexpected comparison (tested on PostgreSQL 9.4 and 9.6) for intervals with a large difference in magnitude.
I narrowed it down to this example, where comparisons with this range give the wrong value:
postgres=# SELECT
'1 year'::interval > '3854933 years'::interval,
'1 year'::interval > '3854934 years'::interval,
'1 year'::interval > '32618664 years'::interval,
'1 year'::interval > '32618665 years'::interval;
?column? | ?column? | ?column? | ?column?
----------+----------+----------+----------
f | t | t | f
(1 row)
Is this a bug? Should I not be comparing intervals? It would seem the interval type has enough information to give the correct answer here.
