Re: Expanding HOT updates for expression and partial indexes

I just spoke to Greg off-list and wanted to share my current thoughts on
the list as well.  In short, while we feel that the patch is in decent
shape and seems to be performance neutral (or maybe even positive in some
cases), it obviously doesn't accomplish $subject, and only a couple of
folks have looked at it in depth.  Furthermore, if this patch was committed
and someone did find a problem, it'd be hard to justify anything except a
revert.  So, it's probably better to keep working on the full patch set and
try to get $subject committed much earlier in the development cycle.

If someone thinks that we should seriously consider committing this for
v19, please let us know.
