That's bad advice. Very bad advice. That is, unless you are ready to delete the cluster and run a new "initdb" after an OS crash. But why risk that, if you can get virtually the same positive effect by disabling "synchronous_commit". But all that shouldn't have a big effect on "pg_restore". To tune "pg_restore", increate "max_wal_size", "checkpoint_timeout" and "maintenance_work_mem". > The other argument I've seen, that if there's a crash during restore you'll have a > corrupted database, is bogus. What are you going to try to do with a database if there's > a crash during restore??? Drop it? You are wrong: it is not the database that is broken after a crash, but the entire cluster.
