pg_sorted_heap 0.13.0 released

pg_sorted_heap 0.13.0 is a PostgreSQL extension release that adds physically sorted heap storage with zone-map pruning, a planner-integrated HNSW vector index (sorted_hnsw), float32/float16 vector types (svec/hsvec), and a stable GraphRAG API surface. The 0.13.0 release stabilizes the narrow fact-shaped GraphRAG contract including functions for ANN seed retrieval, multi-hop relation expansion, and exact reranking. It also introduces multi-shard routing entry points, a low-memory index build mode (build_sq8), and benchmark results showing sub-1.5ms query times with 100% Recall@10 on high-dimensional workloads. Targeted at time-series, IoT, and RAG applications that want vector search inside PostgreSQL without a separate sidecar.
