It might be.  PostegreSQL or another open source database system might
add a similar feature later, or the new feature might be adapted to be
partially usable with current open source software.

I still think it is the intention of OSD #9 to prevent this.  If we
consider External Deployment distribution, you are attempting to
attempting to mandate that only an open source database program can be
distributed in conjunction with your program.  This still seems to
contradict OSD #9, which says, "The license must not place restrictions
on other software that is distributed along with the licensed software."
 Finding otherwise would require that the modified program and Oracle be
considered a single derived work; I just don't think this is accurate
(if it was Oracle would probably sue).
