Yes, for 6.6.  There are some other INSERT ... SELECT cases that can't
be fixed until we have separate targetlists for the INSERT and the
source SELECT --- but I did take care of this particular issue.  The
column relabeling etc doesn't happen until after we've finished with
analyzing the SELECT subclause.
