Standing notes

Plausible uses a custom entrypoint.postgres.sh.tmpl that auto-runs pg_upgrade --link on major version changes — single-step major upgrades are safe and automatic. Do NOT skip more than one major postgres version at a time (e.g. 13→14 is fine; 13→15 is two steps and risks data corruption).
The plausible app image moved from plausible/analytics on Docker Hub to ghcr.io/plausible/community-edition starting with v2.1.x. The v2.0.0 image is still on Docker Hub as plausible/analytics:v2.0.0.
ClickHouse version must be compatible with the plausible app version. Check release notes when upgrading either. The 23.4.2.11-alpine image works with plausible v2.0.0.
Recipe version label convention: <recipe-semver>+<app-version> (e.g. 3.0.1+v2.0.0).
For postgres major upgrades: bump DB_ENTRYPOINT_VERSION in abra.sh to force config re-deploy if entrypoint script changes. Current is v1 (handles 13→14 and beyond via pg_upgrade).
TOTP_VAULT_KEY env var was added in v2.1.x — not needed for v2.0.0.
