I was watching a very large recursive CTE get built today and this CTE
involves on the order of a dozen or so "loops" joining the initial
table against existing tables. It struck me that - every time through
the loop the tables were sorted and then joined and that it would be
much more efficient if the tables remained in a sorted state and could
avoid being re-sorted each time through the loop. Am I missing
something here? I am using PG 8.4 if that matters.
