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

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

Could this be due to the OP's build of PG using floating point timestamps?I don't know why this query returns false:It works for me:
SELECT '20040506 070809.010000'::timestamp(6) - '20010203
040506.007000'::timestamp(6) = '1188 day 3 hour 3 minute 3 second 3
millisecond'::interval;
If I just subtract the two timestamps, its result is the interval I
specified.
What may cause this?
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)
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
