Josh, I've had cold feet about this patch from day one, and have not
been very shy about expressing it, for instance here
http://archives.postgresql.org/pgsql-hackers/2008-05/msg00122.php
here
http://archives.postgresql.org//pgsql-hackers/2008-09/msg01662.php
and here
http://archives.postgresql.org//pgsql-hackers/2009-01/msg01928.php
(those are just samples from long threads in each case).
Despite all that arm-waving, no one besides KaiGai-san has really
stepped up to work on it. That leaves me not only with worries about
the patch itself, but with an extremely low estimate of the community's
interest in it. And it is too big, complicated, and risky to go in
if there's not strong community support for it.
