Optimizing PostgreSQL Query Performance and Indexing Strategies

# Optimizing PostgreSQL Performance Database latency is often the primary bottleneck in web application throughput. Understanding PostgreSQL indexing strategies can dramatically cut response times. ## Index Types & Recommendations - **B-Tree Indexes**: Ideal for equality and range queries on IDs, timestamps, and numbers. - **GIN Indexes**: Recommended for array columns and JSONB search payloads. - **Composite Indexes**: Use multi-column indexes for queries filtering on combined predicates like `where: { status: "PUBLISHED", publishedAt: { lte: now } }`.
