Interesting. But after looking at,
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).
