Do you think it would be better to change d_type to this?
CREATE TYPE d_type AS
(
xi double precision,yi double precision,xe double precision,ye double precision,id integer
);
Note: This is NOT something I want to do but if there is no other way to form d_type tuple from the variables...

Suppose I had the data that form the returning tuple in 5 variables like this:float8 xi = 1;float8 yi = 2;float8 xe = 3;float8 ye = 4;int32 id = 1;In addition the function wouldn't have any input parameters. It just returns a tuple of type d_type.Can you tell me how it is possible to form the tuple? My problem here is that I DON'T have HeapTupleHeaders i and e already formed (those two are of p_type) so I have to form them somehow.
