Re: [COMMITTERS] pgsql: Install some slightly realistic cost estimation

Hi Tom,

I hate to slow you down when you're coding, but it'd be cool if you
could explain to me (and other interested parties) what's going on here :)

Is this totally rad bitmap index support going in? :D Does it require
new index types or does it work with existing ones, etc?
