You can get the seconds using extract and then do further manipulation.
To get fractional hours you can use the example below. To get hours and
minutes you can use modular arithmatic and concatenate to build the
desired string.
area=> select extract(epoch from '1 day 02:30'::interval) / 3600;?column?
---------- 26.5
(1 row)
