The PostgreSQL Query Planner

Why does my query need a plan? Sequential scan vs. index scan. Join strategies. Join reordering. Using EXPLAIN. Row count and cost estimation.

Things the query planner doesn't understand. Things that are nearly always slow. Redesigning your schema. Upcoming features and future work.
