I've added another function, partly to aid debugging, partly to test the
next part of the project.
The idea is simple. select the results of the calculation into a local
variable and then process it. However, I can't get the select to work.
The failure message relates to the "select into D" line.
gary=# select * from read_breakdown(1);
