You can do substraction on dates.
SELECT ending - starting FROM intervals;
SELECT * FROM intervals WHERE ending - starting > 86400::timespan;
If you want something more sophisticated, you have to read the dates into a
program (I do it with Perl) and use this program to perform all the operations
you wish.
