I'm curious if anyone's considered adding logic to count actual disk/cache
hits to report for EXPLAIN ANALYZE so that we get a more apples-to-apples
comparison?
The other question is whether anyone has got scripts or tools or what not
for testing and getting accurate numbers for the following tuning variables:
random_page_costcpu_tuple_costcpu_index_tuple_costcpu_operator_cost
I've seen the code and the last one is pretty gross, but the first three
could definitely swing the optimizer, especially with the hardware I might
be getting ;-)
If noone has scripts, can anyone suggest how to implement.
