Sorry, but I did not want to start a flaming war against the TODO list with my first message. In all the other open source projects I have contributed code, the TODO list is always a start point to newcomers. There's no explicit message in the Postgresql TODO list saying that the projects there are hard, stuck or undesirable. So it's very confusing to a newbie who just want to help and try to learn something in the process.
And now I don't know If I should continue to work on the issue on my first message and post my ideas on the list, or if I should find other ways to contribute, for example, fixing bugs from the bug list.
Regards,
Antonio Belloni
