Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database. It is part of the Java Standard Edition platform and provides methods to query and update data in a database, and is oriented towards relational databases.

PostgreSQL® JDBC Driver (pgJDBC for short) allows Java programs to connect to a PostgreSQL® database using standard, database independent Java code. Is an open source JDBC driver written in Pure Java (Type 4), and communicates in the PostgreSQL® native network protocol. Because of this, the driver is platform independent; once compiled, the driver can be used on any system.

The current version of the driver should be compatible with PostgreSQL® 8.2 and higher using the version 3.0 of the PostgreSQL® protocol, and it’s compatible with Java 8 (JDBC 4.2) and above.

This manual is not intended as a complete guide to JDBC programming, but should help to get you started. For more information refer to the standard JDBC API documentation. Also, take a look at the examples included with the source.
