Thanks all for your responses.
That is, Oct 26 is a daylight savings transition day im my area. Postgres
interpret interval '1 day' equal to 24 hours and Oct 26 day has 25 hours, so
the day doesn't change.
To add exactly 1 day to any date I do this, such as Tom Lane suggests:
s001=> select '26/10/2003'::date + 1;
?column?
------------
27/10/2003
(1 row)

Is that your daylight savings time changeover point (appears to be from
the output, but it's worth checking). IIRC '1 day' is taken as equivalent
to 24 hours which because of the time zone switch causes the above (it'd
presumably be 27/10/2003 00:00:00 CEST but that's not your timezone
anymore).

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
