I'm not sure this would have helped.  If you see this in the error 
message, then there is no additional guidance what a "stand-alone 
composite type" and a not-"stand-alone composite type" are.

Maybe it's possible to catch the forbidden cases more explicitly and 
come up with more helpful error messages along the lines of "cannot 
create a typed table based on the row type of another table".
