Interesting. But after looking at http://www.varlena.com/GeneralBits/96.php,
it appears that PostreSQL's main problem was its BSD license, and the fact
that it entitles third parties to include postgre in commercial products.
More importantly, "IBM does have a policy enabling open source projects
to use its patents approved by the Open Source Initiative."
I don't know the details, but I'd expect IBM's policy not to interfere
with their Public License (i.e. OpenAFS's license).
