Well I agree, it would be a tough job. I can try and break the patch into
several self-complete incremental patches which compile and work, but
I am worried about missing something somewhere and/or inserting
any bugs in the process.


I suppose inserting HOT tuples without index maintenance is useful even if
no
changes to the space allocation is made is useful. It won't get the space
usage but it would save on index thrashing. But that still implies all the
code to handle scans, updates, index builds, etc. Those chunks could be
separated out but you can't commit without them.



There are few things that we can separate easily, like CREATE INDEX
related changes, VACUUM and VACUUM FULL related changed, space
reuse related changes etc. Let me give it a shot.

Thanks,
Pavan
