When does this happen?

IF When running multiple Docker Compose projects that use PostgreSQL, the default volume name 'metamcp_postgres_data' may collide with other Postgres volumes, causing data corruption or container startup failures.

How others solved it

THEN Rename the volume in docker-compose.yml to a unique name, e.g., 'myapp_metamcp_postgres_data'. This avoids global volume name conflicts.

volumes:
  myapp_metamcp_postgres_data:
    driver: local
