Long time without write here, I've been very bussy but now I've got good news. The proyect I have talking about was aproved in pgFoundry in that way we can keep all in order: all the code, the mail list and others useful resources in the same site. Personally, I'm very happy to help an OpenSource project like PostgreSQL, like I said time ago, even so I haven't got a full time work for this, I do the best I can. Many thanks to my friend alvherre for the help in this project.
