Hi, I'd like to use postgres to store my secret data in a way that only me (the DBA, owner of the table) can access the talbe while the root (system administrator) who installed and maintains the server - will not be able to see the data. Now, I think that "db authentication" is simply not enough , because the administrator can copy the data files to his own machine (where he is the owner of the database). Is there a way to protect the data files, so even the "malicious administrator" cannot see the data ? tnx, zferentz
