It seems I'm confusing myself and everyone else around me at the moment
:)

Ok lets have a go at explaining.

I have to two databases 'provision' and 'order' there are no
relationships/keys between the two. From your definition of cluster, I
_think_ I mean that there is cluster called 'foo' and there are two
slony 'sets' - id = 1 (provision), and id = 2 (order).

Is the right approach?
