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...*
O
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 t

Maybe you're missing HeapTupleGetDatum() there? Just from a data type
cleanliness standpoint, you shouldn't ever assign something to Datum or
vice versa without applying the correct conversion macro
I see what you mean and I changed the code BUT still my main problem is that
I want to know how to fill values array. I remind you that d_type contains
attributes of another composite type p_type.
I need a solution to that because I need to use it in other parts of the
code.

Seems like the main problem with that function is that you're passing
an uninitialized "nulls" array to heap_form_tuple.
I kinda wonder why you are using a fixed-length values array toge
I have these types:
CREATE TYPE p_type AS
(
x double precision,
y double precision
);
CREATE TYPE d_type AS
(
i p_type,
e p_type,
id integer
);
CREATE OR REPLACE FUNCTION d_swap(d_type)
RETURNS d_type
AS '/home/user/PostgreSQL/9.0/lib/mylib','d_swap'
LANGUAGE C STRICT;
My problem is that I do
