Incorrect (describe the problem):
-- Comment explaining what makes this slow/problematic
CREATE INDEX users_email_idx ON users(email);
SELECT * FROM users WHERE email = 'user@example.com' AND deleted_at IS NULL;
-- This scans deleted records unnecessarily
Correct (describe the solution):
-- Comment explaining why this is better
CREATE INDEX users_active_email_idx ON users(email) WHERE deleted_at IS NULL;
SELECT * FROM users WHERE email = 'user@example.com' AND deleted_at IS NULL;
-- Only indexes active users, 10x smaller index, faster queries
