Обсуждение: Libpq.dll library and its distribution in other products

Hello PostgreSQL Team,

I'm writing this email on behalf of Charonware company whose product
CASE Studio 2 Database Design Tool supports PostgreSQL database,
including PostgreSQL 8.1 version (you can see the news at:
http://www.postgresql.org/about/news.494).

I'd like to ask you for your assistance concerning libpq.dll library and
other .DLL files.
These files are not distributed with our software and our customers are
asked to install them separately from the PostgreSQL package to be able
to reverse engineer the PostgreSQL database in our product.
(For PostgreSQL 8.1 they also need other .dll files: tcomerr32.dll,
krb5_32.dll, libeay32.dll, libintl-2.dll, libiconv-2.dll and ssleay32.dll.)

Our customers would very appreciate if they can avoid installation of
the libraries to our product. Therefore I'd like to ask you if it's
possible to distribute these libraries within our product. If so, what
the conditions are and what we are supposed to do to get the permission.

Thank you very much for your reply. I've tried to find some information
on this issue on your website, however I wasn't successful. If you can
point me out to the right direction, I'd be very happy. Thanks very much.

I look forward to hearing from you soon.

Kind regards,

Vladimira Nitrova &
CASE Studio 2 Team

As far as Postgres files are concerned, you can distribute them freely
with your products, no strings attached; they are released under the
"new" BSD license (no advertising clause).  This covers libpq.dll; I
think no other file in that list is copyright PGDG, thus you need to
investigate elsewhere.

For example I think the OpenSSL files are typically distributed under
"old" BSD license, and thus require a mention in your advertising
materials, etc.  ("This product contains software developed by OpenSSL
etc")

Read our FAQ on the license.
