Yeah yeah absolutely nothing. Just like any other feature committed to
Postgres so far ;-)
I need to polish the chain conversion patch a bit and also add missing
support for redo, hash indexes etc. Support for hash indexes will need
overloading of ip_posid bits in the index tuple (since there are no free
bits left in hash tuples). I plan to work on that next and submit a fully
functional patch, hopefully before the commit-fest starts.
(I have mentioned the idea of overloading ip_posid bits a few times now and
haven't heard any objection so far. Well, that could either mean that
nobody has read those emails seriously or there is general acceptance to
that idea.. I am assuming latter :-))
Thanks,
Pavan
