Use Coolify-managed PostgreSQL over SQLite
The /deep-design session chose SQLite on a persistent volume for its zero-ops
simplicity at this scale. Deploying on Coolify changes the calculus: Coolify
provides managed PostgreSQL with automatic scheduled backups, whereas a
SQLite file inside an app volume has no managed backup and forces a
single-instance, stop-then-start deploy strategy to avoid file-lock contention
when Coolify briefly runs old and new containers during a rolling restart. We
switch to Coolify-managed PostgreSQL (via Drizzle's pg driver).
Consequences
- Backups are handled by Coolify's database backup feature — no bespoke tooling (e.g. Litestream) needed.
- Deploys no longer need a recreate/single-instance constraint; the app can restart freely while Postgres persists as a separate service.
- Adds a Postgres service to local dev (
docker-compose) and a managed DB in prod — one more moving part than a single file. - Supersedes the SQLite choice in DESIGN.md (T5, F10) and the original
/deep-designdecision. - Unchanged: deploys must not auto-run from
main(every merge would deploy); use a tagged release or manual trigger.
