Validation Queries:

-- Verify connection
SELECT version();
SELECT current_database();
SELECT current_user;

-- Test basic query
SELECT 1 + 1 AS result;

-- Test parameterized query (via \set)
\set id 1
SELECT * FROM users WHERE id = :id;

Success Criteria:

• All queries return expected results
• No errors or warnings
• Performance is acceptable

Test 2: Python psycopg2 Integration

Script (test_psycopg2.py):

#!/usr/bin/env python3
import psycopg2

# Connection parameters
conn_params = {
    'host': '127.0.0.1',
    'port': 5432,
    'user': 'postgres',
    'password': 'postgres',
    'dbname': 'heliosdb',
    'sslmode': 'require'
}

try:
    # Connect
    print("Connecting to HeliosDB Nano...")
    conn = psycopg2.connect(**conn_params)
    cursor = conn.cursor()

    # Test 1: Simple query
    cursor.execute("SELECT version()")
    version = cursor.fetchone()[0]
    print(f"✅ Connected! Version: {version}")

    # Test 2: Parameterized query
    cursor.execute("SELECT $1::int + $2::int AS sum", (5, 7))
    result = cursor.fetchone()[0]
    assert result == 12, "Parameterized query failed"
    print(f"✅ Parameterized query: 5 + 7 = {result}")

    # Test 3: Prepared statement
    cursor.execute("PREPARE test_stmt AS SELECT $1::text || $2::text")
    cursor.execute("EXECUTE test_stmt('Hello', ' World')")
    result = cursor.fetchone()[0]
    assert result == "Hello World", "Prepared statement failed"
    print(f"✅ Prepared statement: {result}")

    # Test 4: Transaction
    cursor.execute("BEGIN")
    cursor.execute("CREATE TEMP TABLE test_txn (id INT, name TEXT)")
    cursor.execute("INSERT INTO test_txn VALUES (1, 'Alice')")
    cursor.execute("COMMIT")
    print("✅ Transaction committed")

    # Cleanup
    cursor.close()
    conn.close()
    print("\n🎉 All tests passed!")

except Exception as e:
    print(f"❌ Error: {e}")
    raise

Execution:

python3 test_psycopg2.py

Expected Output:

Connecting to HeliosDB Nano...
✅ Connected! Version: HeliosDB Nano v2.1.0
✅ Parameterized query: 5 + 7 = 12
✅ Prepared statement: Hello World
✅ Transaction committed

🎉 All tests passed!

        password: 'postgres',
        database: 'heliosdb',
        ssl: { rejectUnauthorized: false }
    });

    try {
        // Connect
        console.log('Connecting to HeliosDB Nano...');
        await client.connect();

        // Test 1: Simple query
        const version = await client.query('SELECT version()');
        console.log(`✅ Connected! Version: ${version.rows[0].version}`);

        // Test 2: Parameterized query
        const sum = await client.query('SELECT $1::int + $2::int AS sum', [10, 20]);
        console.log(`✅ Parameterized query: 10 + 20 = ${sum.rows[0].sum}`);

        // Test 3: Transaction
        await client.query('BEGIN');
        await client.query('CREATE TEMP TABLE test_node (id INT)');
        await client.query('INSERT INTO test_node VALUES (42)');

        String user = "postgres";
        String password = "postgres";

        try (Connection conn = DriverManager.getConnection(url, user, password)) {
            System.out.println("Connecting to HeliosDB Nano...");

            // Test 1: Simple query
            Statement stmt = conn.createStatement();
            ResultSet rs = stmt.executeQuery("SELECT version()");
            if (rs.next()) {
                System.out.println("✅ Connected! Version: " + rs.getString(1));
            }

            // Test 2: Prepared statement
            PreparedStatement pstmt = conn.prepareStatement(
                "SELECT ?::int + ?::int AS sum"
            );
            pstmt.setInt(1, 15);
            pstmt.setInt(2, 25);
            rs = pstmt.executeQuery();
            if (rs.next()) {
                System.out.println("✅ Prepared statement: 15 + 25 = " + rs.getInt("sum"));
            }

            // Test 3: Transaction
            conn.setAutoCommit(false);
            stmt.execute("CREATE TEMP TABLE test_java (id INT)");
            stmt.execute("INSERT INTO test_java VALUES (99)");
            conn.commit();
            System.out.println("✅ Transaction committed");

            System.out.println("\n🎉 All tests passed!");

        } catch (SQLException e) {
            System.err.println("❌ Error: " + e.getMessage());
            e.printStackTrace();

🐛 Known Issues & Workarounds

Issue 1: Self-Signed Certificate Warnings

Symptom: SSL certificate verification warnings Workaround: Use sslmode=require instead of verify-full for testing Resolution: Install CA-signed certificate for production

Issue 2: Connection Timeout on First Connect

Symptom: First connection takes longer than subsequent ones Cause: Server initialization and certificate loading Workaround: Normal behavior, subsequent connections are fast
