RESOLVE First I remove dir data/postgres and create again, then I removed all

images and rebuilded and up again

Answer 1

Default postgres Docker image entrypoint takes parameters directly, you should omit postgres in the command sequence.

version: '3'

services:
  postgres:
    image: postgres:12-alpine
    ...
    command: >
      -c work_mem=256MB
      -c maintenance_work_mem=256MB
      -c max_wal_size=1GB
    ...
