Re: Getting interval in seconds?

Thanks!

Which is better/faster?

select date_part('epoch',('now'::timestamp - somedate)::interval) from
sometable;

Or

select extract (epoch from interval ('now'::timestamp - somedate)) from
sometable;

Should I be using 'now'::timestamp or some function form of it?

Cheerio,
