Update DB_URL format in downloader

[areguig]

The DB_URL environment variable passed to typetype-downloader was using a JDBC connection string (jdbc:postgresql://...), but the downloader is a Go service that expects a standard PostgreSQL DSN (postgres://...). This caused the service to crash on startup.

Thanks for catching this.

The direction looks right: the downloader is a Go service, so it should not receive a JDBC URL.

Before merging, could you also update docker-compose.dev.yml? It still passes:

DB_URL: jdbc:postgresql://postgres:5432/typetype_downloader

so the same startup issue would remain in the dev/beta compose stack.

One small consistency point too: after moving credentials into DB_URL, DB_USER and DB_PASSWORD are still set separately to typetype. If the downloader reads DB_URL first, those become redundant or potentially misleading. I think we should either remove them or align them with the same env vars used in DB_URL.

Expected shape would be something like:

DB_URL: postgres://${DATABASE_USER:-typetype}:${DATABASE_PASSWORD:-typetype}@postgres:5432/typetype_downloader

applied consistently to both production and dev compose files.

Thanks for catching that missing update . And thank you for creating and sharing this tool. It works incredibily well for such a young software . i will be using this daily and will try to do my best to help when needed .

Thanks for the update :)

I added a tiny follow-up commit so we can avoid making you go back and forth again.

It keeps both compose files consistent: the downloader now gets a direct Postgres DSN with sslmode=disable, and I removed the old DB_USER / DB_PASSWORD entries since they are not used when DB_URL is already a postgres:// URL.

Thanks again for spotting the downloader startup issue :p
