Autovacuum keeps PostgreSQL healthy — but when it’s blocked , backlogged or slow your database performance suffers. This session explains why autovacuum falls behind, how to detect it early, and what tuning and operational fixes can restore balance. Ideal for DBAs and developers managing production databases.
