Обсуждение: License question

Hi Haim,

Is the PostgreSQL license (http://www.postgresql.org/licence.html) LGPL 
compatible? I have adapted some code (for jdate manipulation) into the 
OLE DB project (LGPL). I have copied over the copyright notice, but now 
I'm thinking that this may not be enough.

On the front page of the site (http://www.postgresql.org/) it says 
"*Licence <http://www.postgresql.org/licence.html>* PostgreSQL is 
distributed under the flexible BSD licence." but the license is not the 
BSD license proper.

It seems close, though not identical, to the X11 license 
(http://www.x.org/Downloads_terms.html), which the FSF define as "GPL 
compatible" (http://www.fsf.org/licenses/license-list.html). Yet, the 
X11 license requires an inclusion of a certain paragraph, which is not 
mandated by the LGPL, and which gives permissions not granted by the GPL.

I'm confused.
