Does MonetDB support window aggregates and window frames?

From the documentation it looks like it supports only window rank functions. Queries of the form: SELECT saleyear, salequarter, sum(saleamount), sum(saleamount) OVER ( PARTITION BY saleyear ORDER BY salequarter ASC) AS partitionedsaleamount FROM ds_1108_null_advent_1580276965 group by saleyear, salequarter; fail with this error: SELECT: function 'sum' not found However, the code seems to include branches that process window aggregates. See sql_parser.y (line 3530) and rel_select.c (line 4658).

I am also seeing a similar issue with window frames: SELECT saleyear, salequarter, EXTRACT (MONTH FROM orderdate) AS monthofsale, SUM(saleamount) AS totalsales, RANK() OVER ( PARTITION BY monthofsale ORDER BY SUM(saleamount) ASC ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) AS rank FROM ds_1108_null_advent_1580276965 GROUP BY saleyear,salequarter,monthofsale ORDER BY saleyear ASC LIMIT 20; TypeException:user.s16_1[60]:'algebra.subsort' undefined in: (_103:any, r1_103:any, r2_103:any) := algebra.subsort(_92:int, r1_100:bat[:oid,:oid], r2_100:bat[:o id,:oid], _83:bit, _99:bit) program contains errors NOTICE: This e-mail message and any included attachments are from Infogix, Inc.
