I'm currently porting an application to rails where I utilize intervals
(as the run time of a movie).  Right now I've just got a Ruby class that
turns the string (eg "01:00:00") given from the database into the number
of seconds (since that's all I really need).  I also opened up
Object::Time and added the ability to + one of my Intervals (just for
convenience).  What Ruby type are you thinking you'd want pg's interval
mapped to?
