Maybe I missed part of the discussion, but do these really need to be
handled like reloptions instead of like datoptions?  Perhaps the
deciding factor is that we want to parse them once and store them in a
cache, so like reloptions; the others are used once per connection and
then thrown away.

If this is the case, then I think we could just decide that their name
is reloptions due to hysterical reasons and be done with it.
