No, I think you have taken it very far already. I think HOT is similar
to a group of patches we are looking at for 8.3 where the implementation
and side-effects are complicated, and are going to take a while to
resolve.

For HOT, I think the basic idea of using UPDATE chains in a single page
is a clear win, but we have to make sure that assumptions made
subsystems are not broken by this. CREATE INDEX is only one case.
Before committing it, we have to be sure we have everything covered.

It is also good you have done performance testing, so we are probably OK
in that area.
