Hi,
are there any plans to support updating a tuple using a sub-select in one of 
the future versions.

e.g, something like:

UPDATE report_table
  SET (order_count,order_value) = (SELECT count(*), sum(amount)
                                   FROM order o
                                   WHERE o.customer_id = 
report_table.customer_id);

I know it's currently not possible (so we need to revert to two sub-selects) but I was 
wondering if this somewhere on the "roadmap"

Regards
Thomas
