* Dates and Times
o Allow infinite dates just like infinite timestamps
- o Add a GUC variable to allow output of interval values in ISO8601
- format
o Merge hardwired timezone names with the TZ database; allow either
kind everywhere a TZ name is currently taken
o Allow customization of the known set of TZ names (generalize the
o Fix SELECT '0.01 years'::interval, '0.01 months'::interval
o Fix SELECT INTERVAL '1' MONTH
+ o Add a GUC variable to allow output of interval values in ISO8601
+ format
+ o Improve timestamptz subtraction to be DST-aware
+
+ Currently, subtracting one date from another that crosses a
+ daylight savings time adjustment can return '1 day 1 hour', but
+ adding that back to the first date returns a time one hour in
+ the future. This is caused by the adjustment of '25 hours' to
+ '1 day 1 hour', and '1 day' is the same time the next day, even
+ if daylight savings adjustments are involved.
+
+ o Fix interval display to support values exceeding 2^31 hours
+ o Add overflow checking to timestamp and interval arithmetic
o Add ISO INTERVAL handling
o Add support for day-time syntax, INTERVAL '1 2:03:04' DAY TO
SECOND
