Download

Binary JAR file downloads of the JDBC driver are available here. Becuase Java is platform neutral, it is a simple process of just downloading the appropriate JAR file and dropping it into your classpath. Source versions are also available here for recent driver versions. Prior to the 8.0 release the JDBC driver was distributed with the server source code.

This is the current version of the driver. Unless you have unusual requirements (running old applications or JVMs), this is the driver you should be using. It supports Postgresql 7.2 or newer and requires a 1.4 or newer JVM. It contains support for SSL and the javax.sql package. It comes in two flavors, JDBC3 and JDBC4. If you are using the 1.6 or 1.7 JVM, then you should use the JDBC4 version.

JDBC3 Postgresql Driver, Version 9.1-901

JDBC4 Postgresql Driver, Version 9.1-901

Many other versions of the JDBC driver are available. This includes development versions, compatibility with older JDKs, and previous versions of the driver.

To determine JDK/JVM compatibility this following list matches up versions of the JVM with the JDBC specification implemented.

• JDK 1.1 - JDBC 1. Note that with the 8.0 release JDBC 1 support has been removed, so look to update your JDK when you update your server.
• JDK 1.2, 1.3 - JDBC 2.
• JDK 1.3 + J2EE - JDBC 2 EE. This contains additional support for javax.sql classes.
• JDK 1.4, 1.5 - JDBC 3. This contains support for SSL and javax.sql, but does not require J2EE as it has been added to the J2SE release.
• JDK 1.6, 1.7 - JDBC4. Support for JDBC4 methods is not complete, but the majority of methods are implemented.
