@wzhfy Given a set of input plans (either base table access or plans over
derived/complex plans), one can build a graph based on the join conditions
among the plans. I think join enumeration should be driven by the presence of
join conditions between two plans. Following this approach, I think we can
detect items that are not connected and plan them towards the end.
