Hi all,

Who can give an authorative answer regarding distributing PostgreSQL 
under a different license?

In particular, the front page claims that PostgreSQL is under the BSD 
license. The problem is that there are two. The four clause license, 
which is not GPL compatible, and the three clause, which is.
Then again, the license itself is neither three not four clause. It is 
somewhat similar to the X11 license, though not identical.

The problem is this:
I'm using some code adapted from the PostgreSQL sources in the OLE DB 
provider, which is LGPL. I am not sure whether the PostgreSQL license is 
LGPL compatible, or what I need to do in order to use it. I have already 
placed copyright notices copied from the file I copied the actual code 
from, but do I need to do anything else? Is it at all possible to do 
this relicensing?
