I have som SQL that in 8.0.3 do:

And in 8.3.5 do:
seg_veh2=# SELECT '@ 32 hours'::INTERVAL;
 interval
------------
 @ 32 hours

Why i unable to get my old style of interval, i really need to see the day part.... im using datestyle german in both.... im try with "SET IntervalStyle TO..." but i get this error:

Even IntervalStyle won't help you here; since recent releases consider
the values "1 day 8 hours" as distinct from "32 hours" (because
they are at certain times of the year in some timezones
where days are 25 hours, etc).

So.. how can i recover my "days" part...

If you tell it what time of year you are thinking of this trick can work:

dish=# set datestyle to german;
SET
dish=# select  '2001-01-01'::timestamp + (interval '32 hours') - '2001-01-01'::timestamp;
   ?column?

-----------------
 @ 1 day 8 hours
(1 row)

Any help it appreciate... thanks :D
