You are right; theoretically, the correct place to document that
would be the VACUUM documentation. But I guess that most people who
are curious about VACUUM's memory usage will read the documentation for
"maintenance_work_mem" or "autovacuum_work_mem".

I have fixed a typo and added a similar paragraph to "maintenance_work_mem".
