Hello

this proposal is related to reported issue
http://www.postgresql.org/message-id/E1VQuta-0007Y4-Ip@wrigleys.postgresql.org

We can directly modify any fields of int, float, double arrays (when result
size will be immutable). This trick is used now for acceleration of some
aggregates.

Ideas, comments?

Regards

Pavel
