Interesting point.  It's doubtless unwise to take this press release as
being an accurate guide to the terms of the license, but what it says
is

: According to the terms of the OIN license, the components covered by
: the agreement include not only the Linux kernel and associated GNU
: applications, but also other open source projects included in Linux
: distributions. 

which to me says you're covered as long as your code is commonly
included in Linux distributions.  Hence, proprietary derivatives
would *not* be covered.  I'd guess that Oracle would have a hard
time suing for any patent violation embedded in the freely
distributed Postgres code, but any technique appearing only in
the proprietary extension would still be at risk.

IANAL, etc.  I assume that EDB and Greenplum will have their
lawyers scrutinizing this deal on Monday morning ;-) ... I'd
be interested to hear what the experts' conclusion is.
