Postgresql – How to convert an interval into a number of hours with postgres

datetimeintervalspostgresql

Say I have an interval like

4 days 10:00:00

in postgres. How do I convert that to a number of hours (106 in this case?) Is there a function or should I bite the bullet and do something like

extract(days, my_interval) * 24 + extract(hours, my_interval)

Best Solution

Probably the easiest way is:

SELECT EXTRACT(epoch FROM my_interval)/3600
