Thanks. I still think it's better for
parallel_vacuum_bulkdel_all_indexes() to return whether it processed
all the indexes or some. Although I'm a bit worried that changing the
return type of the function could impact anyone reusing parallel
vacuum code from the core, this is not a complex change to adopt. So,
I did that in the attached v3 patch. Please have a look.
