How to reformat output of "age()" function

[David Gauthier]

How can I change the default output of the "age" function to be, for
example, in minutes?

E.g.
dvdb=> select age('2019-09-11 09:00:00','2019-09-09 11:00:00');
      age
----------------
 1 day 22:00:00
(1 row)

I want the equivalent of that time delta in minutes.

Thanks in Advance
