Is this a third party application or something you've developed? If it's third party, you'd need to talk to the vendor because the application will have to be updated to support Owner Names.
If you were using a newer version of PSQL (PSQL v 8.5 or later), you could use Database Security to limit access to the files. It wouldn't be encrypted but would prevent a user from getting to the files.
