Remove some long-obsolete code that was causing a strange error message

when someone attempts to create a column of a composite datatype.  For
now, just make sure we produce a reasonable error at the 'right place'.
Not sure if this will be made to work before 7.5, but make it act
reasonably in case nothing more gets done.
