Well, his point is that old versions of his client code wouldn't know to
do that. However, I don't think that what he's suggesting is a suitable
answer either --- he wants to rely on a chance coincidence, namely that
we're upgrading the FE/BE protocol at the same time that he wants to
make an incompatible application-level change.
What I'd do, if I wanted to lock out old clients from accessing
particular tables, is just rename the tables to something else.
(Or keep using the same names, but put the tables in a schema or
database that old clients won't look in.) The clients wouldn't fail
very gracefully, perhaps, but the protocol-level hack doesn't qualify
as graceful in my book either ...
