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".

Drop it?
You are wrong: it is not the database that is broken after a crash, but the entire cluster.
