Just out of curiosity I've also tried tpc-c from oltpbench (in the very same
simple environment), it doesn't show any significant difference from master as
well.

While testing the latest version I've noticed, that you didn't include the fix
for HeapTupleInvisible (so I see the error again), was it intentionally?

Yes, please. I've tried it myself for reviewing purposes, but the rebasing
speed was not impressive. Also I want to suggest to move it from github and
make a regular patchset, since it's already a bit confusing in the sense what
goes where and which patch to apply on top of which branch.
