Postgresql Database Engineering

This is production PostgreSQL knowledge packaged up: indexing strategies, query optimization with EXPLAIN, partitioning for tables with 100M+ rows, and replication setup. It covers the stuff you actually need when databases get serious, like MVCC internals, VACUUM operations, choosing between B-tree and BRIN indexes, and connection pooling with pgBouncer. The skill walks through when to use each index type (GIN for JSONB, BRIN for time-series) and replication modes (synchronous vs asynchronous tradeoffs). Honestly most useful if you're already past basic SQL and dealing with performance problems or scaling challenges. Not a tutorial, more like having a senior database engineer's decision framework at hand.
