There aren't any. PostgreSQL is under the 3-clause BSD license.

If you don't want your customers to see it, don't ship it to your
customers. That's true whether you use PostgreSQL or not.

None, no matter what they purport, and you won't be able to build one
either. You should also consider carefully what it is you're telling
your customers by starting off with an adversary relationship. If
your data is that secret and that valuable, you should not ship it in
the first place.
