It seems like this should error to me:
CREATE ACCESS METHOD heapdup TYPE TABLE HANDLER heap_tableam_handler;
CREATE TABLE likeam1() USING heap;
CREATE TABLE likeam2() USING heapdup;
CREATE TABLE likeamlike(
LIKE likeam1 INCLUDING ACCESS METHOD,
LIKE likeam2 INCLUDING ACCESS METHOD
);
At the very least, the documentation should say that the last one wins.
