Postgres init scripts (optional)

Files here are mounted into the Postgres container at /docker-entrypoint-initdb.d/ and run only on first startup (when the data volume is empty), in alphabetical order.

01-schema.sql — creates pgvector extension and RAG tables (stories, documents, chunks).
To add more users or other setup, add scripts with names like 00-create-user.sql (they run before 01-schema.sql).
To disable init: in docker-compose.yml, comment out the postgres volume that mounts this folder, or remove/rename the .sql files.

After the first run, these scripts are not executed again. To re-run them, remove the volume: docker compose down -v (this deletes DB data), then docker compose up -d.
