first_value/last_value

[Tom Smith <tomsmith1989sk@xxxxxxxxx>]

Hello:

Is there a plan for 9.7  to enable using the two aggregate function

as non-window function?   i.e.  enabling getting the first/last row

in single sql without using window features.

There is actually a  C-extension for first()/last().  

I am wondering  if 9.7 would make them built-in function like max/min

Thanks
