Always one row with group by / agregate

Stepping through
dip=> create table t ( x int , y int );
CREATE
dip=> select x,min(y) from t group by x;
x|min
-+---
|
(1 row)
select min(y) should return one row with a null value, but it's
expected. I thought that the first part of the job was to process
the group by and then the select on each group, but it doesn't
seem to be the case.
