I've pushed this after adjusting the int array to become an AttrNumber array.

I toyed with the idea of having the loop iterator in
ExecInitIndexOnlyScan() an AttrNumber type, but in the end went with a
cast. I felt this way was more robust against any possible future
widening of the AttrNumber typedef.  I added the cast to prevent any
compilers from warning about truncation.  This can't happen since
indnkeyatts is int16, but I don't know if all compilers would be able
to figure that out, so added a cast.

Thank you to both of you for reviewing this.
