Hi all,
Somewhy fsync does not work for me.

Yes, they are both your packages from your official site. So this means that
in 8.2 and in earlier versions the rounding is not the regular one.

Thanks Tom for your comments.
I meant the build in this directory:
http://www.postgresql.org/ftp/binary/v8.3.6/win32/, and the builds for win32
of other versions in the binary directory.
What is the trend of these builds regarding floating point timestamps? For
example what about 8.4?
Thanks,

Thanks, It's off in both 8.2 and 8.3.
What will be the default in 8.4?

I mean the Win32 distribution on the PgSql site. I always used that.
It would be very good if these data types were exact by default, even if
that's a bit slower.

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?

Hi,
I don't know why this query returns false:
SELECT '20040506 070809.01'::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?

Hi all,
Pg 8.0.3 allows me to compare interval with integer, but I cannot see any
reasonable rule:
These are true:
1 < '1 days'::interval
2 > '1 days'::interval
999 > '1 days'::interval
1999 < '2 days'::interval
2000 != '2 days'::interval

Situation:
