Perhaps there is more to do here? Sorry, I did not understand the
details of Alvaro's post [1], but I did not recognize the difference
between ExecuteGrantStmt and ExecSecLabelStmt so it was my impression
either one or both of these places are either wrongly commented, or
maybe are doing something that should not be done.

There was no reply for 9b. Was it accidentally overlooked, or just
chose not to do it?
