It can't be toasted because pg_class hasn't got a toast table. I can't
recall at the moment whether there's a fundamental reason for that or
it's just an oversight.

No, because that would not improve the error message. All it would do
is prevent relacl from making use of a pg_class toast table, when and if
we get around to adding one.
