Having trouble scanning this. Since hstore isn't nested what the heck does
"nested assignment" mean w.r.t. hstore?
It means assigning to one "subdatum" in the hstore datum, as opposed
to simply assigning an entirely new hstore (granted, that's what
you're actually doing with the nested assignment, but conceptually
you're assigning to a "subdatum" when using the "hstore ||" idiom that
the hstore docs prominently talk about).
I could argue at least as convincingly that what the jsonb || operator
does is exactly analogous to what hstore's || does.
