Upgrading postgres docker

[krschacht]

We just merged in a commit which upgrades the version of postgres in the docker image. After I pulled this commit down to my local dev environment, I got an error telling me that my database was not compatible with this version of postgres.

The easiest way to fix this is to blow away docker and re-run docker compose up.

1. I opened Docker Desktop and went through each of the sections: Containers, Images, Volumes, Builds. I deleted everything that mentioned "hostedgpt"
2. I ran docker compose up in one terminal tab. It pulled down the image and rebuilt everything. I saw some database query errors as things were starting up, which surprised me.
3. Just to be safe in another terminal tab I ran docker compose run base rails db:setup. It seemed like it was already setup by this point so I don't think that was necessary.

After this, just http://localhost:3000 and sign up again.
