Potential docker compose portability issue

[d3287t328]

Describe the bug
On a Windows 11 host running wsl and ubuntu I had the issue that the memgpt_db-1 would fail to start correctly. I had to modify the compose.yaml file to get it to work a new volume with the lines:

volumes:
      - pgdata:/var/lib/postgresql/data
...
volumes:
  pgdata:

fixed the issue. I realize this may be a Windows specific issue in WSL but it would be good to document a solution to this issue.

Please describe your setup

• How did you install memgpt?
  git clone and latest sources

• Describe your setup

  • What's your OS (Windows/MacOS/Linux)?
  • How are you running memgpt? (cmd.exe/Powershell/Anaconda Shell/Terminal)

Bash shell ubuntu wsl.
