fwiw, we have a lot of materialized views, so restoring a DB on non-vacuumed tables caused the materialization to take a lot longer than it would have with autovacuum running as normal. Seems worth experimenting though.

Exactly.

Good clarification. I personally have never had occasion to move a partial cluster, so my use of "database" in my question was sloppy, I meant "cluster". So yes, I'd delete the cluster and initdb if I ever actually had an OS crash during a pg_restore--which in 20 years of using PG has never happened. I suppose it might matter more if one were forced to run one's db on an unstable platform ;-)
