Hi all,
I'm wondering what people think of introducing some kind of function
to extract the number of units between 2 dates? At the moment there's
no way to do this. Take the following example:
Event 1 is '1985-10-26 01:22:00'
Event 2 is now.
How many minutes between these 2 events? What I don't want is how
many years, months, days and hours there are between them.
This could potentially involve implementing age(timestamp, timestamp,
interval), like:
postgres=# SELECT age(current_date, '1985-10-26 01:22:00'::timestamp,
'1 second') as age_in_seconds;
age_in_seconds
----------------
798733367
(1 row)
Is this easily done?
Thanks
