Small nit - I get this from the following query: postgres=# select a, sum(a) over (order by a) from generate_series(1,10) a; a | sum ----+----- 1 | 55 2 | 55 3 | 55 4 | 55 5 | 55 6 | 55 7 | 55 8 | 55 9 | 55 10 | 55 (10 rows) >From what I can tell of the spec, the 'sum' column should contain a running sum (ie 1,3,6 etc). You mention that window frames haven't been implemented, but it seems like this case should return an error rather than the wrong results...
