2008-10-07	Extend CTE patch to support recursive UNION (ie, without ALL). The	Tom Lane
	implementation uses an in-memory hash table, so it will poop out for very large recursive results ... but the performance characteristics of a sort-based implementation would be pretty unpleasant too.
2008-10-04	Implement SQL-standard WITH clauses, including WITH RECURSIVE.	Tom Lane
	There are some unimplemented aspects: recursive queries must use UNION ALL (should allow UNION too), and we don't have SEARCH or CYCLE clauses. These might or might not get done for 8.4, but even without them it's a pretty useful feature. There are also a couple of small loose ends and definitional quibbles, which I'll send a memo about to pgsql-hackers shortly. But let's land the patch now so we can get on with other development. Yoshiyuki Asaba, with lots of help from Tatsuo Ishii and Tom Lane
