If I read the code correctly, the VACUUM PARALLEL option is capped by 
the active max_parallel_maintenance_workers setting.  So if I write 
VACUUM (PARALLEL 5), it will still only do 2 by default.  Is that 
correct?  The documentation (VACUUM man page) seems to indicate a 
different behavior.

I haven't been able to set up something to test or verify this either way.
