Обсуждение: SQL5 budget
Hi, all. I had preliminary conversation with my employer about implementation of SQL5 [1] without "Driven Scene" [2]. He needs concretebudget. So i'm asking you to estimate and say, how much will it cost. In particular, speach goes about implemention of slides # 17-42, 47-56, 63, 102-109, 114-143, 147-157, 160-177, 180-197 of "sql5.16.4.pdf", and about implementation of http://sql50.euro.ru/site/sql50/en/author/mtd_eng.htm [1] http://sql50.euro.ru/sql5.16.4.pdf Brief description of SQL5 is on http://blogs.ingres.com/technology/2008/07/31/bringing-dbms-in-line-with-modern-communication-requirements-sql2009 or on http://sql50.euro.ru/site/sql50/en/author/resume_eng.htm [2] http://computer20.euro.ru/driven-scene.pdf Brief description of SQL5 is on http://blogs.ingres.com/technology/2008/07/31/new-step-in-office-technologies-driven-scene or on http://computer20.euro.ru/site/computer20/en/author/driven-scene_eng.htm

I think you're barking up the wrong tree here; the community can't really do hacking for hire. If you want to pay for something to be implemented (which is great!), you'll need to talk to companies that do Postgres consulting. You can find examples on the website and through google. You could also try posting to pgsql-jobs.

Except that it's not a job offer - it's more of a "solicitation for
implementation of something," so I'm not sure that's the right place
either.
Some of the things suggested seem interesting, but many seem (to me)
to be overly tied to an "all XML all the time" view. I really rather
have PostgreSQL head towards being "more relational" (in the 3rd
Manifesto sense) than take the "all singing, all dancing XML" road.

No, but that's where the right people would see it.
Realistically, this means most likely contracting with 2nd Quadrant,
Command Prompt or Peter Eisentraut.
However, keep in mind that no hacker can guarentee you that any patch
will be accepted, even one based on the SQL standard.
BTW, why do you want these features?

In searching back to the archives, it becomes evident that I shouldn't have been as polite as I was, and that it is indeed mainly nonsense. There *would* be merit in supporting the work on recursive queries, in 8.4, as that will help when trying to build queries that are to return hierarchical result sets.
