How should your application handle a serialization failure?

Serialization failures (error code 40001 in PostgreSQL) are expected and retryable — they indicate a conflict that would violate serial execution order. Application handling: 1) Catch the serialization_failure exception. 2) Roll back the current transaction (it's already invalid). 3) Retry the entire transaction from scratch with a brief delay. 4) Implement exponential backoff: retry 1 after 100ms
