Nice explanation! Thanks! I wish Postgres official docs had link to this video :)

Great presentation! I never really considered the effect of page compression on the BRIN index but I will definitely in the future. One important question though: in your benchmarks you use work mem as your variable - how might someone optimise this in practice, given that work_mem is deprecated in v7?
