I don't believe that works (anyone who thinks I'm wrong, please correct me).
You will need to use select syntax, e.g. "select * from
setreturningfunction(param1, param2,....);" If you are using ODBC, you may
have a problem with that syntax, though I believe that the driver code has
been patched to deal with that, and a new release is on its way out (or you
could compile the source).
