Right, and this master password is only protected because Oracle is
closed source. It is not possible to do the same thing with Postgres
because you could find the master key (or the algorithm to produce it)
in the source code.
However this amounts to "security by obscurity", and anyone serious
about encryption will tell you it is insufficient. There is no way to
have cryptographically sound protection of your data using a key
embedded in the software like that.
