A PostgreSQL function is not a stored procedure in the
same sense as in Oracle or MS SQL Server, for example,
so you cannot use the syntax you would use for those.
You need to use normal SQL select syntax, i.e. "select
testcallsp()", and the return value comes back as a
recordset (which happens to have one column and one
row).
