If I recall correctly, Jim Nasby was considering it; he hadn't heard
much interest back, and got to other things in the 8.2 cycle.

There has been some discussion on strategy for an approach to it for
the 8.3 cycle; you can expect that not to progress much 'til 8.2.0
gets released.

Bringing it back up on pgsql.hackers, some time soon thereafter, would
be not the worst idea of all time :-).
