Does this syntax look correct? Can anyone think of a better way to write
this?

This function will accept two timestamp parameters and determine the highest
of the two?

create or replace function fcn_max_dt(p_dt timestamp without time zone,
                                      p_dt2 timestamp without time zone)
returns timestamp without time zone as $$
  DECLARE
      v_dt timestamp without time zone;
      v_dt2 timestamp without time zone;

  BEGIN
    v_dt := p_dt;
    v_dt2 := p_dt2;

    if v_dt >= v_dt2 then
    return v_dt;
    else
    return v_dt2;
    end if;

  END;
$$ LANGUAGE 'plpgsql';
