The documentation does not say this.  Instead, there's the following
rather explicit explanation that only OS crashes matter:

| (Crashes of the database software itself are not a risk factor
| here. Only an operating-system-level crash creates a risk of
| corruption.)

If it really matters how PostgreSQL is shut down in "fsync = off" mode
(while the operating system keeps running), the documentation is
seriously wrong here.
