Is there a reason you can't do that now with a limit 1/order by/union all?
Just have it ordered one way on the first query and the other on the bottom. That will give you two rows that are the first / last in your set based on whatever column you order on.

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
