BTW I would like to push 0001 and 0002 to master/18. They are are not
behaviour changes, they just fix up a bunch of inconsistent (0001) and
misleading (0002) variable naming and comments to reflect reality (in
AIO v1 the postmaster used to assign those I/O worker numbers, now the
postmaster has its own array of slots to track them that is *not*
aligned with the ID numbers/slots in shared memory ie those numbers
you see in the ps status, so that's bound to confuse people
maintaining this code). I just happened to notice that when working
on this dynamic worker pool stuff. If there are no objections I will
go ahead and do that soon.
