[Q] Distributing a binary of postgres with my software and license

Hi,

I am working on a web application where the backend data is stored in a
PostgreSQL db. A PHP application is the UI into the DB. I want to
distribute this application in a CD-ROM so that people can still use it
off-line.

I was thinking of shipping a CD along with an installer. The installer
would install a web server + the php engine on the client coumputer. I
want to ship a binary version of PostgreSQL along with the CD. I have a
few questions:

1. Is it possible to embed a postgresql db into an application like I
mention. Perhaps as a DLL (WinDOS) or as a .so (unix)? Ideally, I do
not want to install a full fledged DB on the client's machine. It would
be nice if my code linked against a DLL/.so which took care of
everything without the need to run a postgresql daemon on the client
machine.

2. My understanding of the BSD license is that it allows this kind of
redistribution. Am I correct?

3. If '1' were possible, can the binary database file be encrupted in
some way? Even a trivial encryption is fine.

Thanks.

S.
