This is not even possible given the variety of hardware, OS variants,
work-loads, database sizes, etc. The answer is really "all of them."
Those who specialize in tuning constantly run test cases to tease out
clues to performance tuning and even they most likely couldn't answer this.
The closest you are likely to come is to read and reread "PostgreSQL
High Performance" which is an invaluable resource.
