9.2 Beta: intersection of daterange

I think result is ok... 2010-01-04 is not inside first range...

Subject: [HACKERS] 9.2 Beta: intersection of daterange
I'm currently doing some tests on range types:

tests=# SELECT int8range(5,15) * int8range(10,20) AS intersection;
intersection
--------------
[10,15)
(1 Zeile)

tests=#
tests=# SELECT '[2010-03-15,2010-05-22)'::daterange *
'[2010-01-04,)'::daterange AS intersection;
intersection
-------------------------
[2010-03-15,2010-05-22)
(1 Zeile)

Does the second query trigger a bug or am I misunderstanding something?

I would expect [2010-01-04,2010-05-22) as result.

Regards,

Brar

Staring at my query for five minutes obviously didn't prevent me from
creating that noise.

I meant to query "SELECT '[2010-03-15,2010-05-22)'::daterange *
'[2010-04-01,)'::daterange AS intersection;" which gives the expected
result.

Sorry for the noise!

Thanks for testing! You've inadvertently done a positive test, which is
a good thing ...
