Hello everybody,

I am trying to define a C function returning tuples to Postgres.
It's easy to define a function like that:

TUPLE f(t)
TUPLE t;
{
   return(t);
}

and reference it :

retrieve (emp.all) where emp.f.salary>300

However, the tuples returned by the f function (that should be identical)
are apparently changed-- the values are different. Could somebody
advise me what's the problem?
Thanks in advance,
Martin
