You could create a new type with the columns you'd like to see:

CREATE TYPE my_type AS
(
this TIMESTAMP NOT NULL
that INT4 NOT NULL,
other VARCHAR(128),
);

CREATE FUNCTION my_function()
RETURNS SETOF my_type IMMUTABLE
AS $_$
DECLARE
the_type my_type%rowtype;
BEGIN
FOR the_type IN
EXECUTE 'SELECT t.this, t.that, t.other FROM my_table WHERE ...'
LOOP
RETURN NEXT the_type;
END LOOP;
RETURN;
END;
$_$ LANGUAGE plpgsql
