:: One advantage of the PostgreSQL JDBC driver is that it is a "Type 4" driver. This means that it is written in Pure Java, so it can be taken anywhere, and used anywhere as long as the platform it is used on has TCP/IP capabilities, because the driver only connects via TCP/IP.[http://www.commandprompt.com/ppbook/c20820]
