CREATE TABLE users_v2 (
id SERIAL PRIMARY KEY,
email. VARCHAR(255) UNIQUE NOT NULL,
password_hash VARCHAR(255) NOT NULL,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
status user_status DEFAULT 'active',
metadata JSONB
);

-- Migrate existing data
INSERT INTO users_v2 (email, password_hash, created_at, status)
SELECT email, password_hash, created_at,
CASE WHEN active THEN 'active'::user_status ELSE
'inactive'::user_status END
FROM users_v1;

-- Create indexes for performance
CREATE INDEX idx_users_email ON users_v2(email);
CREATE INDEX idx_users_status ON users_v2(status);
CREATE INDEX idx_users_metadata ON users_v2 USING GIN (metadata);

COMMIT;

Real-world Application: A social media platform's DevOps team implements automated database scaling and backup procedures, ensuring zero data loss during a 10x traffic spike while maintaining sub-second query response times.
