Why pgJDBC?
The PostgreSQL JDBC Driver allows Java programs to connect to a PostgreSQL database using standard, database independent Java code. pgJDBC 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.
Latest Releases
Current release is 42.7.14. Security release: fixes requireAuth being silently not enforced when the value excludes every authentication method (CVE-2026-107314), and the driver storing bytes of earlier statements when it pads a value shorter than its declared length (CVE-2026-107315). See the Changelog for details
pgJDBC allows Java programs to connect to a PostgreSQL database using standard, database independent Java code.
pgJDBC provides a reasonably complete implementation of the JDBC specification in addition to some PostgreSQL specific extensions.
The current development driver supports eleven server versions and three java environments.
Processing a simple query
This example will issue a simple query and print out the first column of each row using a Statement.
Statement st = conn.createStatement();
ResultSet rs = st.executeQuery("SELECT * FROM mytable WHERE columnfoo = 500");
while (rs.next()) {
System.out.print("Column 1 returned ");
System.out.println(rs.getString(1));
}
rs.close();
st.close();
