Recommended action: Increase shm: docker run --shm-size=256m (compose shm_size; Kubernetes: mount an emptyDir with medium: Memory at /dev/shm), or reduce parallel workers / maintenance_work_mem for the operation.
Option: Raise /dev/shm [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. docker run --shm-size=256m postgres
2. compose: shm_size: 256mb
3. k8s: volumes: [{name: dshm, emptyDir: {medium: Memory}}] mounted at /dev/shm
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
