Thank you for the comment.

FWIW, in my opinion if tte current behavior of 'N(a,b)' could confuse
users and we want to break the backward compatibility, I'd rather like
to remove that style in PostgreSQL 10 and to raise an syntax error to
user for more safety. Also, since the syntax 'a, b' might be opaque
for new users who don't know the history of s_s_names syntax, we could
unify its syntax to '[ANY|FIRST] N (a, b, ...)' syntax while keeping
the '*'.
