What has been discussed is nested statements, like: SELECT a, count(*) FROM (INSERT <foo> RETURNING a, b) GROUP BY a; But I don't think that's implemented (the interactions with triggers havn't been worked out I think) > Amk I doing anything wrong or is there some missing sentence in the > documentation? When the docs talk about an "expression" they don't mean aggregates, since they are not functions in the ordinary sense.
