CTAS would be safe to do that with. CLUSTER and VACUUM FULL are already done.

Outside of a transaction block would be automatic.

Inside of a transaction block we could use a parameter called
initially_frozen. This would act same as FREEZE on COPY. Parameter
would not be recorded into the reloptions field on pg_class, since it
is a one-time option and has no meaning after end of xact.

Historically we've chosen not to allow bulk insert options on INSERT,
so that is a separate discussion.
