This last statement inserts every record from tableA
into temptable. This follows from the PostgreSQL
"implicit from-clause" feature, whereby "select
tableA.FieldA" is equivalent to "select FieldA from
tableA".
What you want is to refer to "Rec.FieldA", which will
give you the single value that you are looking for.
