Hello,
Currently on the wishlist [1] we have the following items as "posponed":
* WITH RECURSIVE hierarchical queries (Gregory Stark)
* SQL:2003 windowing queries (Gavin)
* Fix permissions properly on custom GUC vars (Andrew Dunstan)
* Create a mechanism for plperl to load modules safely (Andrew Dunstan)
* Notification payload messages (Andrew Dunstan)
* Better handling of partitioning (Nikhils)
I have already moved "updatable views" to the newly created 8.4 wishlist
[2]. Please let me know if any item is infact not posponed or should be
moved to the 8.4 wishlist.
regards,
Lukas
