Thanks for the review and testing.
Attached is v4. It changes documentation and comments only, so the
code is identical to the v3 you tested. The leave-one-out recipe
was too long and didn't handle database scoping properly, so I
removed it. Also, I rewrote and trimmed some comments and
documented two caveats, one about cross-row consistency and the
other about aggregate slot xmin contribution. Patch v4 applies to
master b5978350222.
