A new JDBC driver for PostgreSQL aimed at supporting the advanced features of JDBC and Postgres
http://impossibl.github.io/pgjdbc-ng
The connection format for the pgjdbc-ng driver is
jdbc:pgsql://<server>[:<port>]/<database>
An example
jdbc:pgsql://localhost:5432/test
The java.sql.Driver class is
com.impossibl.postgres.jdbc.PGDriver
The driver will accept configuration parameters in the style of
jdbc:pgsql://localhost:5432/test?applicationName=MyApp&networkTimeout=10000
The javax.sql.DataSource class is
com.impossibl.postgres.jdbc.PGDataSource
, the javax.sql.ConnectionPoolDataSource class is
com.impossibl.postgres.jdbc.PGConnectionPoolDataSource
and the XADataSource class is
com.impossibl.postgres.jdbc.xa.PGXADataSource
The driver and data sources supports the following configuration properties (name, type and default value).
host (String) localhost
The 'host' parameter specifies the host name of the database server. Data sources only.
port (int) 5432
The 'port' parameter specifies the port number of the database server. Data sources only.
database (String)
The 'database' parameter specifies the name of the database on the database server. Data sources only.
user (String)
The 'user' parameter specifies the user name.
password (String)
The 'password' parameter specifies the password.
housekeeper (boolean) true
The 'housekeeper' parameter specifies if the JDBC driver should keep track connections, statements and result sets and automatically close them if they can't no longer be reached.
parsedSqlCacheSize (int) 250
The 'parsedSqlCacheSize' parameter specifies how big the cache size for parsed SQL statements should be.
preparedStatementCacheSize (int) 50
The 'preparedStatementCacheSize' parameter specifies how big the cache size for PreparedStatement instaces should be.
applicationName (String) pgjdbc app
The 'applicationName' parameter specifies the application name associated with the connection on the database server.
clientEncoding (String) UTF8
The 'clientEncoding' parameter specifies the client encoding for the database server.
networkTimeout (int) 0
The 'networkTimeout' parameter specifies the default timeout in milliseconds for the connections. A value of 0 indicates that there isnt a timeout for database operations.
strictMode (boolean) false
The 'strictMode' parameter specifies if the JDBC driver should follow behavior assumed by certain frameworks, and test suites. See http://github.com/impossibl/pgjdbc-ng/wiki/StrictMode for additional details.
pgjdbc-ng is released under the 3 clause BSD license.
The driver is built with maven. Simply build with:
mvn clean package
This will produce, in the target directory, two JAR files. One with dependencies packaged inside and another without.
The unit tests need a PostgreSQL database to execute against. The tests assume theses defaults:
SERVER: localhost
PORT: 5432
DATABASE: test
USERNAME: pgjdbc
PASSWORD: test
The following system properties are supported in order to customize the setup
pgjdbc.test.server
pgjdbc.test.port
pgjdbc.test.db
pgjdbc.test.user
pgjdbc.test.password
If you'd like to build the driver without running the unit tests use the command:
mvn clean package -DskipTests
