Putting aside arguments like "it is not a good idea to use * because

building ROWs, for example in plpgsql triggers or in conditions for
big update statements:
IF (NEW.* EXCLUDING ( last_modified ) ) IS DISTINCT FROM (OLD.*
EXCLUDING ( last_modified ) ) THEN NEW.last_modified =
clock_timestamp() ; END IF
That's a very good use case. I could certainly have used this in the past.
cheers
