I've written a new version of the vacuum streaming read user on top of the rebased patch set [1]. It differs substantially from Andres' and includes several refactoring patches that can apply on top of master. As such, I've proposed those in a separate thread [2]. I noticed mac and windows fail to build on CI for my branch with the streaming read code. I haven't had a chance to investigate -- but I must have done something wrong on rebase.
