Hmm, like what?  I'm not sure how would it work for tables; you'd have
to add the options during _PG_init or something like that, and I haven't
tried it.  It's mainly for user-defined AMs that this was done.

I'm now playing with adding "namespaces" to the options, but that's for
handling options for toast tables.  I'm not really sure how would it
work for regular options.
