Title: Added formular for PostgreSQL JDBC driver.

By default, only the JDBC 3 driver will be installed, which is completely implemented.
The drivers for JDBC 4 and JDBC 41 are not complete, but the majority of JDBC methods are implemented.
Both can be installed in addition to the default.

See: http://jdbc.postgresql.org/download.html for details
