This PR updates the docker-compose installation documentation and env
sample to improve the setup experience.
- Updates the URLs for raw files to reference main branch, which is
likely where new users will be pulling from initially. This seems to be
the most straightforward option; assume that advanced users who want to
retrieve it from a particular tag will know to change the URL for their
scenario.
- Fixes an improperly stated curl command.
- Adds a note that the PGPASSWORD_SUPERUSER should be URL-safe. This is
required since the value is later concat into a PG_DATABASE_URL as a
URL, and expected to be in proper URL format. Touches on #8597.
