Add items from Tom:

<     o Add a GUC variable to allow output of interval values in ISO8601
<       format
212a211,223
>     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
