I think it's related to the plpgsql "RETURNS" and "RETURN" confusion.
RETURN can appear between "begin", "end".
RETURNS need to specify before "AS".
not omit "RETURNS real" would be:
CREATE FUNCTION sales_tax(subtotal real, OUT tax real) returns real AS $$
BEGIN
tax := subtotal * 0.06;
END;
$$ LANGUAGE plpgsql;
