Actually, a deferrable constraint cannot be used with ON CONFLICT DO
NOTHING either, which makes this a pre-existing documentation bug,
that should be fixed and back-patched separately as follows:
- includes an <literal>ON CONFLICT DO UPDATE</literal> clause.
+ includes an <literal>ON CONFLICT</literal> clause.
In addition, I think we should change the word "arbitrators" to
"arbiters". It means pretty-much the same thing, but the latter is the
term used everywhere else.
I'll take care of that separately, so the above diff won't be needed
in this patch.
