I can try your suggestion, but I'd rather want to know why it doesn't
work with the record, when you try to build it your self. It worked
fine when you selected into the record.
But speaking of that, If I try like you did:
SELECT INTO retval <some expression build from the variables tmp.id,
_c3, _c2 that constitutes a row>
RETURN NEXT retval;
wouldn't that work?
I think I need some help with the syntax for the expression above...
I will also try to create a datatype of my own and see if that works
as a last way out.
