No, I need to provide you with a 41 version.

Dave,

Thanks for the quick response. Unfortunately now I'm getting error
with the JDBC driver.

warning: /usr/local/pgsql/share/postgresql-9.4-1204-jdbc42-20151023.230759-1.jar(org/postgresql/Driver.class): major version 52 is newer than 51, the highest major version supported by this compiler.
  It is recommended that the compiler be upgraded.

$ java -version
java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.14.04.1)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

Probably I should upgrade Java...
