Hi,
On 8.2 this comparision is also not true:
select '240:0:0.3'::interval = '10 0:0:0.3'::interval;
But without milliseconds it's true.
Is this also because interval is represented internally as a floating point value?
On 8.3 this test does not fail.
Best regards,
Otto

<havasvolgyi.otto@gmail.com>Thanks.
I tested the standard Win32 distribution of 8.3.6.
The same happens on 8.2. But on 8.0 it works.
When I don't use milliseconds, then it works.
Will 8.4 work fine on Win32 again?
Thanks,
Otto

I don't know why this query returns false:

If I just subtract the two timestamps, its result is the interval I
specified.
What may cause this?
It works for me:
test=> SELECT '20040506 070809.010000'::timestamp(6) -
'20010203 040506.007000'::timestamp(6)=
'1188 day 3 hour 3 minute 3 second 3 millisecond'::interval;
?column? ----------
t
(1 row)
Could this be due to the OP's build of PG using floating point timestamps?
That's what I'm thinking
SELECT ('20040506 070809.010000'::timestamp(6) - '20010203 040506.007000'::timestamp(6) - '1188 day 3 hour 3 minute 3 second 3 millisecond'::interval) * 1e10;
=> -00:01:28.220986
