Re: HOT latest patch - version 8

Please see updated version of the patch. This includes further code
refactoring and bug fixes.

heapam code is now refactored and I have also added several comments
in that code as well as vacuum and create index related code.

In the previous version, we were not collecting aborted heap-only
tuples since they are not part of any chain. This version deals with
such tuples.

There is also some cleanup in the VACUUM FULL area. Especially
we have dealt with the redirected line pointers by pointing them to
the first non-dead tuple in the chain. Since we hold exclusive lock
on the relation, we can easily do that.

Anyways, we still need a comprehensive writeup, but if someone
wants to test things further, this patch should be used.

Thanks,
Pavan
