You can find these changes in the v33 patch.

I mentioned cost delay parameters propagation only in "The Autovacuum Daemon"
chapter. I am not sure that we also should write about parallel workers in the
"Vacuuming" chapter (within cost based parameters description) since VACUUM
PARALLEL doesn't do so.

The only change in the 0001 patch is removing redundant empty line
inside autovacuum.c .
