recursive SQL and with clause

I was just wondering when we could reasonably expect recursive SQL to be
added to Postgres?

I saw some posts from 2004 that made it sound like it was imminent, but I
guess something went wrong?  I believe the WITH clause is a pre-requisite
for recursive SQL, however I do find the WITH clause also very useful in
decomposing very complex SQL into understandable chunks.

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 :-).

I was working on it for 8.2, but it didn't make it.  Mark Cave-Ayland
will probably be picking it up for 8.3.
