I've said what I wanted to say. As long as the community is
comfortable with the reality that this concatenate operator really
isn't useful for assignment within UPDATEs for most jsonb users, then
I can leave it at that. I think that this concatenate operator may
have been informally promoted as the thing that made it possible to do
jsonb UPDATEs in a declarative fashion, but as things stand that
really isn't true.
If nothing changes, let's not make the mistake of going on to
*formally* promote this concatenate operator as offering the ability
to do jsonb UPDATEs in a declarative fashion, because that would be
quite misleading.
