I read this just today, and was reminded of this thread: https://cloud.google.com/blog/products/databases/alloydb-for-postgresql-under-the-hood-adaptive-autovacuum It reads: "1. Transaction ID wraparound: PostgreSQL transaction IDs or XIDs are 32-bit unsigned integers that are assigned to each transaction and also get incremented. When they reach their maximum value, it would wrap around to zero (similar to a ring buffer) and can lead to data corruption." -- Peter Geoghegan
