I believe previous versions actually allowed you
to (if memory serves), but the developers currently
disabled this statement because it could sometimes
cause incorrect results. At:
http://www.postgresql.org/docs/todo.html
you'll find several references to this problem:
* -INSERT ... SELECT ... GROUP BY groups by target
columns not source columns
* redesign INSERT ... SELECT to have two levels of
target list
Hope that helps,
