Postgresql connection error

Hello, I'm novice in DbVis. I've installed Postgresql 9.5.0 as OS X application (http://postgresapp.com -- "Postgres.app is a simple, native Mac OS X app that runs in the menubar without the need of an installer. Open the app, and you have a PostgreSQL server ready and awaiting new connections. Close the app, and the server shuts down.") and got the following error during connection process: ------------------------ Product: DbVisualizer Free 9.2.14 [Build #2495] OS: Mac OS X OS Version: 10.11.2 OS Arch: x86_64 Java Version: 1.8.0_60 Java VM: Java HotSpot(TM) 64-Bit Server VM Java Vendor: Oracle Corporation Java Home: /Applications/DbVisualizer.app/Contents/PlugIns/jre.bundle/Contents/Home/jre DbVis Home: /Applications/DbVisualizer.app/Contents/java/app SessionId: 366 An error occurred while establishing the connection: The selected Driver cannot handle the specified Database URL. The most common reason for this error is that the database URL contains a syntax error preventing the driver from accepting it. The error also occurs when trying to connect to a database with the wrong driver. Correct this and try again. ------------------------ I updated jdbc driver up to 9.4-1207 from postgresql.com, but have not success. Can anybody explain, what is error reason? Thank in advance.
