I don't have any personal experience with it, but it's my
understanding that it's only opensource in the "published opensource
product" sense. Meaning it's not really something that solicits (or
even accepts? ast least not easily...) contributions from the outside.
And forgive me for being negative, but I think you're going to have an
even harder time to get Oracle to accept a contribution if the
motivation for having it is to make the PostgreSQL driver work
better...
