Nonsense.
regression=# SELECT '1 year'::timestamp = '360 days'::timestamp; ERROR: invalid input syntax for type timestamp: "1 year"
How about telling us what you *really* did, instead of posting faked examples?
Sorry: it's an errata. The query is, actually:
SELECT '1 year'::interval = '360 days'::interval;
Sorry about the inconvenience.
There are some contexts in which an interval (not a timestamp) of 1 month will be taken as equivalent to 30 days, for lack of any better idea, but it's not the case that Postgres doesn't know the difference.
regards, tom lane
Thanks.
