I don't think you need to set wal_sync_method, comment it out.

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?

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.

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,

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.

A generated a big SQL script (about 20 Mb), and fed it to psql. I was very

Hi,
Is it normal that when I select for update a record, but I don't select all
the fields, that the contents of fields not selected will be deleted:
create table pidtest(pid integer, szoveg text) without oids;
select pid from pistest where pid5 for update;
After committing (autocommit),
it, but yesterday I was suprised that the
szoveg field's contents in the locked records went away.

Thank you Tom.
It was a bit confusing because my WHERE clause looked something like this:
... WHERE date_field - current_date '21 days'::interval;
And then I got records, whose with date_field's year was 2010. :-o
Now I am using this formula:

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
2001 '2 days'::interval
...
20999 '21
