Declaring the tuple structure of a record in PL/pgSQL

Question

I can\'t find anything in the PostgreSQL documentation that shows how to declare a record, or row, while declaring the tuple structure at the same time. If you don\'t define

Answer 1

There might be some way that avoids the explicit type declaration, but offhand the best I can come up with is:

CREATE TYPE my_func_return AS (
    a integer,
    b varchar
  );

CREATE OR REPLACE FUNCTION my_func()
  RETURNS my_func_return AS $$
DECLARE
  r my_func_return;
BEGIN
  SELECT 1, 'one' INTO r.a, r.b;
  RETURN r;
END; $$ LANGUAGE plpgsql;

Oh, I almost forgot the simplest way to do this:

CREATE OR REPLACE FUNCTION my_func2(out a int, out b text)
  RETURNS RECORD AS $$
BEGIN
  SELECT 1, 'one' INTO a, b;
  RETURN;
END; $$ LANGUAGE plpgsql;
