Is there an good way to extract the interval unit that were used?
E.g. I used interval '2h' and another case I used '3d', theses are respectively 2 hours and 3 days, but the format that came on select is '02:00:00' for hour and '3 days' for days
What I'm looking for is something like 2h and 3d just as inserted. The only solution so far I could came up with is call to_char function using the unit of time and get the highest position for each couple of digits. Ex: to_char(interval, 'DDHH24') let's suppose the result is 0003 then I know it's 3 hours if I get 0100 I know it's 1 day.
