I agree that a "directed graph"-like performance map
would be difficult to be written or understood.
What i think would be ideal (helpful/feasible)
is some kind of documentation of the algorithms involved
in the planner/optimizer, along with some pointers
to postgresql.conf parameters where applicable.
This way we will know
- Why something is happening
- If it is the best plan
- What tuning is possible
