I did see that, although it's plausible that an analogous change would be helpful in core postgres. The readme seemed to suggest that they tried this on cstore_fdw because that was easier on which to develop, not because there was more low-hanging fruit.

It sounds like it was precisely because there was more low-hanging fruit. I think column-store databases are far more amenable to vectorised processing. I'm not aware of any row-store databases which do it, and most research into it has been on column-store (or hybrid) systems.
