Precompiled versions of the driver can be downloaded from the PostgreSQL® JDBC web site. Alternatively you can build the driver from source, but you should only need to do this if you are making changes to the source code. To build the JDBC driver, you need gradle and a JDK (currently at least jdk1.8). If you have several Java compilers installed, ...
To use the driver, the JAR archive named postgresql-MM.nn.pp.jar needs to be included in the class path, either by putting it in the CLASSPATH environment variable, or by using flags on the javacommand line. For instance, assume we have an application that uses the JDBC driver to access a database, and that application is installed as /usr/local/li...
Out of the box, Java does not support unix sockets so the PostgreSQL® server must be configured to allow TCP/IP connections. Starting with server version 8.0 TCP/IP connections are allowed from localhost . To allow connections to other interfacesthan the loopback interface, you must modify the postgresql.conf file’s listen_addressessetting. Once yo...
When creating a database to be accessed via JDBC it is important to select an appropriate encoding for your data. Many other client interfaces do not care what data you send back and forth, and will allow you to do inappropriate things, but Java makes sure that your data is correctly encoded. Do not use a database that uses the SQL_ASCII encoding. ...
The syntax for the connection url is: jdbc:postgresql://host1:port1,host2:port2/database. The simple connection fail-over is useful when running against a high availability postgres installation that has identical data on each node. For example streaming replication postgres or postgres-xc cluster.
