Another example that shows how much of an impact can this make with big

{{{
explain analyze Select a.the_geom && b.the_geom from
benchmark_4c7214d90a79aa6760367a084a4d4a2f61fbe1c6cc4f7f9e76020 a,
benchmark_4c7214d90a79aa6760367a084a4d4a2f61fbe1c6cc4f7f9e76020 b;
-- Before latency average = 423.047 ms
-- After latency average = 0.886 ms
-- Perf: 477.47x
