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
