Well, at PGCon I talked with someone who worked on the
implementation in Oracle 20-some years ago. He said they had a team
of 20 people full time working on the feature for years to get it
working. Now, I think the PostgreSQL community is a little lighter
on its feet, but without more active participation from others than
there has been so far, I don't intend to take another run at it.
I'll be happy to participate at such point that it's not treated as
a second-class feature set. Barring that, anyone else who wants to
take the patch and run with it is welcome to do so.
