Use VALUES?
regression=# create function foo() returns int as $$
regression$# declare s int := 0;
regression$# r record;
regression$# begin
regression$# for r in values (1),(2),(3),(4) loop
regression$# s := s + r.column1;

regression$# end$$ language plpgsql;
CREATE FUNCTION
regression=# select foo();
