PostgreSQL 11 Associate PostgreSQL 11 Associate candidates often miscalculate transaction isolation levels, confusing READ COMMITTED with SERIALIZABLE behavior. Many stumble over MVCC (Multi-Version Concurrency Control) mechanics? particularly snapshot visibility rules when concurrent transactions interact. Indexing strategy questions trip up those unfamiliar with B-tree limitations and when partial indexes actually help. Expect scenarios requiring you to diagnose slow queries using EXPLAIN output, where misinterpreting buffer hits versus disk reads costs valuable points.
