Transaction ID Wraparound in PostgreSQL – Understanding, Mitigating, and Preventing Database Disasters

Shailesh Rangani, Practice Lead for PostgreSQL

Transaction ID wraparound is a critical issue that can affect PostgreSQL databases due to the limited 32-bit transaction ID (XID) space. As transactions occur, the XID value increases until it reaches its maximum limit and wraps back to zero. This inevitable wraparound poses severe risks to database integrity, data consistency, and transactional operations.

In this session, we will explore the PostgreSQL transaction ID wraparound issue in-depth, focusing on its causes, impacts, and advanced mitigation strategies. The topics covered include:

  • Understanding XID Wraparound
  • Technical Mechanics of XID System
  • Causes of XID Wraparound
  • Impacts of XID Wraparound
  • Predicting, Preventing, and Fixing XID Wraparound
