would it be correct something like? or how would you write this?

create or replace function my_function () returs integer as
$$
declare
  ...
  status boolean;
  ...
begin
  ...
  loop
    begin
      set transaction isolation level serializable;
      ...
      do_something();
      ...
      status := true;
    exception serialization_failure
      status := false;
    end;

    if status then exit;
  end loop;
  ...
  return 0;
end
$$ language plpgsql
