I don't get what users would need ago(interval) -> timestamp. That 
function would not make any sense since there is no equivalent to now() 
which returns timestamp, simply because a timestamp does not refer to 
any specific point in time and can only be interpreted with some 
additional piece of information like a time zone.

That said I can't get too excited about this patch since it is just a 
shorter way to write e.g. now() - interval '1 day'. It would also be 
quite funny to see all uses of ago('-1 day') for tomorrow.
