No title

Hi,

PostgreSQL is released under the "PostgreSQL License", a liberal Open
Source license, similar to the BSD one:

http://www.postgresql.org/about/licence/

So you can include PostgreSQL in your commercial applications
and sell them. But you must explicitly specify that your application is
based on
PostgreSQL RDBMS.

Hope it helps,

Giuseppe.

I assume your question is about licensing issues. Please see
http://www.postgresql.org/about/licence/. It is pretty clear - you can do
pretty much anything.

No problem. Here are the requirements of the license:

you need to include the specified copyright and two paragraph disclaimer
in your copyright notices, if you're distributing any derivative of
PostgreSQL, otherwise, there are no strings attached.

Yet there is ONE file (src\backend\parser\gram.h) that goes into the server directory (postgresql\include\server\parser\gram.h) which has a Bison exception in its license that might affect everything that is delivered with this file.

The exception says:
Bison Exception:
"As a special exception, you may create a larger work that contains part or all of the Bison parser skeleton and distribute that work under terms of your choice, so long as that work isn't itself a parser generator using the skeleton or a modified version thereof as a parser skeleton. Alternatively, if you modify or redistribute the parser skeleton itself, you may (at your option) remove this special exception, which will cause the skeleton and the resulting Bison output files to be licensed under the GNU General Public License without this special exception."

So my understanding is that I must take this file out from the deliverable. Isn't that correct?
Thanks
Hemy

No, it isn't.

If you were to generate Postgres' grammar with a custom-modified Bison,
then this wording might require you to honor GPL as well as BSD terms
of distribution for the result. Nobody does that though. Per the
above statement, we can distribute the files generated by stock versions
of Bison under terms of our choice, to wit the Postgres license.

Were this not the case, we wouldn't be using Bison.
