PostgreSQLas well?<br /><br /> Interesting point. It's doubtless unwise to take this press release as<br /> being an
accurateguide to the terms of the license, but what it says<br /> is<br /><br /> : According to the terms of the OIN
license,the components covered by<br /> : the agreement include not only the Linux kernel and associated GNU<br /> :
applications,but also other open source projects included in Linux<br /> : distributions.<br /><br /> which to me says
you'recovered as long as your code is commonly<br /> included in Linux distributions. Hence, proprietary
derivatives<br/> would *not* be covered. I'd guess that Oracle would have a hard<br /> time suing for any patent
violationembedded in the freely<br /> distributed Postgres code, but any technique appearing only in<br /> the
proprietaryextension would still be at risk.<br /><br /> IANAL, etc. I assume that EDB and Greenplum will have
their<br/> lawyers scrutinizing this deal on Monday morning ;-) ... I'd<br /> be interested to hear what the experts'
conclusionis.<br /><br /> regards, tom lane<br /><br /></font>
