/**
 * Optional single-tenant Postgres store (ADR 0020, #84): the relational,
 * multi-writer path for self-hosters who already run Postgres and have
 * outgrown DuckDB's single read-write process. It carries the **full** analytics
 * surface — no stubbed aggregates — by rendering the same dialect-agnostic
 * builders with {@link postgresDialect} (ASOF joins emulated via `LATERAL`,
 * daily rollups recomputed at query time) and executing them over a pooled
 * `pg` connection. Events live in the wide `events` table (plus the dedicated
 * `node_samples`); metadata (projects, API keys, scene registry) is re-homed
 * into the same database.
 *
 * The schema is migrated on creation (migrations are idempotent, forward-only
 * and serialized behind an advisory lock, so several collector instances can
 * boot against one database). Connection settings come from
 * `readDbSettings().postgres` (`POSTGRES_URL` / `DATABASE_URL`, `POSTGRES_SCHEMA`,
 * `POSTGRES_POOL_MAX`).
