I think you have cleaned only in gram.y as I could see the references
to 'including' in other parts of code. For ex, see below code:

There seems to be code below the above check which is not directly
related to opclasses, so not sure if you have missed that or is there
any other reason to ignore that. I am referring to following code in
the same function after the above check:
/*
* If a key type different from the heap value is specified, update
*
the type-related fields in the index tupdesc.
*/
if (OidIsValid(keyType) &&
keyType != to->atttypid)
