Recommended action: SET maintenance_work_mem high enough (without exhausting server memory) before CREATE INDEX; increase max_parallel_maintenance_workers; in Docker make --shm-size at least maintenance_work_mem for parallel builds; build after bulk loading.
Option: Raise maintenance_work_mem (and shm) for the build session [evidence: official_recommended_action]
Applies when: Large HNSW builds
Steps:
1. SET maintenance_work_mem = '8GB';
2. SET max_parallel_maintenance_workers = 7;
3. docker run --shm-size=8g ... (if containerised)
Expected: Graph fits in memory; faster build
