computations should adjust based on the time zone rules.

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

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

+ o -Add support for day-time syntax, INTERVAL '1 2:03:04' DAY TO

SECOND

+ o Fix SELECT INTERVAL '1' MONTH

o Add support for year-month syntax, INTERVAL '50-6' YEAR TO MONTH

o For syntax that isn't uniquely ISO or PG syntax, like '1:30' or

'1', treat as ISO if there is a range specification clause,
