Postgresql Performance Tuning | Postgresql DBA Training

In this video, we will understand one of the most critical PostgreSQL production issues called Transaction ID Wraparound. Learn how PostgreSQL transaction IDs work, why autovacuum is important, how long-running transactions create wraparound risk, and why databases suddenly become slow even when CPU usage looks normal. We will also cover VACUUM FREEZE, dead tuples, table bloat, relfrozenxid, datfrozenxid, MVCC architecture, real-time production troubleshooting steps, and important DBA interview concepts with practical examples. This video is very useful for PostgreSQL DBAs, developers, cloud engineers, and anyone working on production PostgreSQL databases.
