When: Is there any official word on when 8.4 will be released? We are working on an enterprise solution with a release date in May and as such, the release date for 8.4 is an important consideration in our planning.
I think targeted date is May '09 and may be delayed beyond that since there is no beta yet. But it's worth the wait. I'm a postgresql end user so I'm guessing here.
What: Is there a more or less definitive list of the new features that will end up in the release? There are 3 features that influenced our decision to go with 8.4 and I would like to read more about the level of certainty with which these will end up in 8.4. The features are 1) WITH clauses, 2) WINDOW-ing functions like SUM() OVER PARTITION BY (), LEAD(), LAG(), etc., and 3) Hierarchical queries.
