/**
 * Shared utilities for the Postgres v-next observability domain.
 *
 * Differences from the ClickHouse v-next helpers:
 *   - jsonb columns are passed through as native objects/arrays. No
 *     JSON.stringify on the way in or JSON.parse on the way out.
 *   - text[] columns are passed as native arrays.
 *   - Timestamps are sent as ISO strings; the pg driver coerces them.
