FWIW, I vote with Robert on this. When and if you actually want to make
that array resizable, it'd be time to introduce use of a DSA. But right
now we need to be looking for simple and reliable solutions for v10.
In particular, since right now dsm_type = NONE is still considered
supported, we can't really have autovacuum facilities that are dependent
on being able to use DSM. That might change in future, but not today.
