You're close, debugging plpgsql can be tricky:

You need a couple of things (untested):

... AS '
BEGIN
  UPDATE update_flag SET content=current_timestamp;
  RETURN ''OK'';
END;
' LANGUAGE 'plpgsql';

The BEGIN...END wrapper is needed as is a value to RETURN. There is an
example of this function in my PostgreSQL Notes at http://techdocs.postgresql.org/
