 ## Supported PostgreSQL and Java versions
 The current version of the driver should be compatible with **PostgreSQL 8.4 and higher** using the version 3.0 of the protocol and **Java 8** (JDBC 4.2) or above. Unless you have unusual requirements (running old applications or JVMs), this is the driver you should be using.

 Most people do not need to compile PgJDBC. You can download the precompiled driver (jar) from the [PostgreSQL JDBC site](https://jdbc.postgresql.org/download.html) or using your chosen dependency management tool:
