Sounds good.
This is important in other situations too, e.g.

Are you implementing the array of parameters on pg_index as Tom
suggested or pg_class.relfillfactor?
Why not implement an array of option parameters on pg_class, so both
heaps and indexes can be given additional parameters? That way you
wouldn't need a specific relfillfactor attribute. That would allow us to
keep CREATE TABLE free of additional keywords also.
