    Backpatch introduction of TupleDescAttr(tupdesc, i).
    
    2cd70845240 / c6293249d change the way individual attributes in a
    TupleDesc are stored / accessed.  To reduce the effort of making
    extensions compatible with postgresql 11, and to ease future
    backpatching, backpatch introduction of TupleDescAttr() to all
    releases.  Do not backpatch change in storage, as that'd be a breaking
    change for existing and working extensions.
