Did anyone try it? I want to know how to scan columnar data in parallel.

I had a little challenge and succeeded.(on pg11beta2) https://gist.github.com/masayuki038/6820f551f1a6d4e1ec7b3929ffad35ad

But I did not implement some methods to handle shared memory.(ex. EstimateDSMForeignScan) Do anyone tell me how to estimate the shared memory size required for parallel scan?
