Hi,

Yes that works but when I try to put the results of a rowtype returning function into a rowtype variable in another
functioni cannot access the individual attributes from variable.  Only from the direct call. 

ie.

x1 := (get_defaults_vals()).a1
x2 := (get_defaults_vals()).a2
x3 := (get_defaults_vals()).a3

i can't do

declare
vals default_vals%rowtype
begin
select get_defaults_vals() into vals;

x1 := default_vals.a1;

I can't do this. Postgresql seems to forget what the attributes are if i put the results into a rowtype variable.

Hello,

my code works well:

CREATE TABLE Foo(a integer, b integer);

CREATE OR REPLACE FUNCTION ret_foo()
RETURNS Foo AS $$
DECLARE r Foo;
BEGIN
  r := (10,20); --default
  RETURN r;
END; $$
LANGUAGE plpgsql;

SELECT ret_foo();

CREATE OR REPLACE FUNCTION trig()
RETURNS TRIGGER AS $$
BEGIN
  NEW := ret_foo();
  RETURN NEW;
END; $$
LANGUAGE plpgsql;

CREATE TRIGGER footrig BEFORE INSERT ON Foo
  FOR EACH ROW EXECUTE PROCEDURE trig();

INSERT INTO Foo VALUES(0,0);

Regards
Pavel Stehule
