Folks, Robert Treat brought this up.
I create a table with something to partition by, and some meaningless junk. I'm trying to get a random ordering inside each window: CREATE TABLE foo(i, t) AS SELECT i, md5((i*generate_series(1,10))::text) /* Nonsense text */ FROM generate_series(10,1) i; SELECT i, t, RANK() OVER ( PARTITION BY i ORDER BY random() ) FROM foo; ERROR: ORDER/GROUP BY expression not found in targetlist Oops. I found this error message only in backend/optimizer/util/tlist.c and am wondering whether there needs to be a different code path for windowing, or...? Any ideas?
