Besides the GPL issue, this is my biggest problem.

My work towards SQL-standard recursive queries is nowhere near complete and
I'm sure any patches I had are severely rotten by now. I'll try to grab
what I had and see if I can get a patch from which people can maybe pick
up.
Sorry for dropping the ball on this one. I was back finishing up my
degree this past year and my current work isn't database-related :( . I'll
see what I can do. This would be a great feature for PostgreSQL.
