// NOTE: provider is temporarily set to "sqlite" for Phase 1 local verification.
// Flip to "postgresql" once Docker + docker-compose Postgres is available.
// All cascade rules and indexes below are portable between providers.
//
// Postgres-only additions applied post-cutover (see packages/db/POSTGRES_FTS.md):
//   * Generated tsvector column on Part(serial, mpn, notes) + GIN index (Phase 3 scope).
//   * WebhookSubscription.events and SavedView.filterJson currently stored as String (JSON
//     text) for SQLite portability; on Postgres these become String[] and Jsonb respectively.
