Bundling pgsql to commercial product

Hi All,

We are thinking of bundling PostgreSQL as part of our commercial product
for windows distribution. For linux distribution administrators would
download it thru their package managers but for windows we would like to
distribute the binaries within our product distribution for painless
installation.

We have been really concern if we are able to do this from licensing point
of view. As our product is under commercial license. I have read a few
articles on this subject that are confirming that we can do this from legal
point of view. Of course I would appreciate if you have any resources
saying that this is bad idea.

My question is if you, community of PosgreSQL, know any commercial licensed
product that is doing the same, shipping the PostreSQL binaries directly
within their product bundle. I would appreciate any leads on this subject.
