Attached is a new version. It's rebased on current git master, including BRIN. I've also fixed the laundry list of small things you reported, as well as a bunch of bugs I uncovered during my own testing.
This patch needs a small rebase, it has been broken by a590f266 that fixed WAL replay for brin indexes: patching file src/backend/access/brin/brin_xlog.c Hunk #2 FAILED at 42. Hunk #3 FAILED at 91.
