This may be a stupid question, but what are datoptions?

$ git grep datoptions

Yeah.  It's particularly unfortunate that we call them "reloptions" in
the code but "storage parameters" in the documentation.  Neither is a
particularly good name, and having two different ones is extra-poor.
But I'm fine with leaving the names as they are and moving on, if no
one objects too much.  Speak now or don't complain about it after I
write the patch!
