我有一个docker-compose文件

postgres:
    container_name: second_postgres_container
    image: postgres:latest
    shm_size: 1g

我想用吸尘器吸table，但得到了ERROR: could not resize shared memory segment "/PostgreSQL.301371499" to 1073795648 bytes: No space left on device
第一个数字比右边的小，而且我在服务器上有足够的空间（只有32%被占用）
我想知道它是否认为docker容器不够大（因为它会根据需要调整大小）？））或者还有什么地方可能有问题？
音符

docker ps  -a
