Transaction ID wraparound cannot be reproduced in short-term testing

Transaction ID wraparound emerges only after months or years of cumulative transaction counts. Cannot be meaningfully simulated in staging, short-lived performance tests, or initial production rollout. Risk easy to overlook during validation phases.

Do not rely on staging or performance testing to validate wraparound safety. Implement production monitoring of age(relfrozenxid) from day one. Verify autovacuum configuration during deployment review. Calculate expected time-to-wraparound based on anticipated write rate.
