Обсуждение: how to get number of minutes?

If I subtract 2 timestamps, how do I get the results returned as the total number of minutes.

example

now() - (now()-'2 hours'::interval) = 2:00:00  -- I need the result returned as 120 minutes.

Thanks,

Chris

select extract(epoch from interval '2 hours')/60;

'epoch' returns the number epoch seconds that comprise the interval.
That differs from 'seconds' which just returns the "seconds place",
which is zero for 2:00:00 of course.
