查询9.3-1102-jdbc41 jar兼容的PostgreSQL服务器版本及相关文档

Hey there! Let me help you out with this question about the PostgreSQL JDBC driver version 9.3-1102-jdbc41.

First, let's unpack what that driver version string tells us:

• The 9.3 segment is tied to the major PostgreSQL server version this driver was originally developed for.
• 1102 is the driver's patch release number, indicating bug fixes and minor updates.
• jdbc41 means it's built for JDBC 4.1, so it requires Java 7 or later to run.

Supported Server Versions #

Officially, this driver version supports PostgreSQL 8.2 and all newer versions. That includes:

• Every server release from 8.2 up to 9.3 (the version the driver is aligned with)
• Most minor releases beyond 9.3 (though you won't get access to the latest server-specific features introduced after 9.3)

PostgreSQL JDBC drivers are designed to be backward-compatible, so connecting to older servers (8.2+) should work without major issues.

Verify Directly with Code #

If you want to confirm this yourself without relying on missing docs, you can run a quick Java snippet to pull the driver's metadata:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.DatabaseMetaData;

public class DriverCompatibilityCheck {
    public static void main(String[] args) {
        String url = "jdbc:postgresql://your-server:5432/your-database";
        String user = "your-username";
        String password = "your-password";

        try (Connection conn = DriverManager.getConnection(url, user, password)) {
            DatabaseMetaData metaData = conn.getMetaData();
            System.out.println("Driver Version: " + metaData.getDriverVersion());
            System.out.println("Minimum Supported Server Version: " 
                + metaData.getDatabaseMajorVersion() + "." + metaData.getDatabaseMinorVersion());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Just replace the placeholder values with your actual database credentials, and it'll output the driver's supported minimum server version.
