Now I'm not writing to_char(interval), because current source (7.1) is
freeze for new features and I'm waiting for 7.2 devel. cycle and I'm spending
time with other things (PL/Python, the Mape project etc..).

If it's *really important* for you I can write it next week(s),
... of course, my time is limited :-)

May be try found some other solution.
