 * PostgreSQL connection layer.
 *
 * FNXC:PostgresConnection 2026-06-24-02:05:
 * Barrel export for the postgres connection subsystem. This module provides
 * backend resolution (embedded vs external), connection pool management with
 * the DATABASE_MIGRATION_URL split, and credential redaction.
 *
 * Consumers:
 *   - The embedded lifecycle feature (U2) calls createConnectionSetFromUrl()
 *     after starting the bundled Postgres.
 *   - The external startup path calls createConnectionSet() with DATABASE_URL set.
 *   - Tests use resolveBackend() and the credential-redact helpers directly.

// FNXC:RuntimeStartupWiring 2026-06-24-11:05:
// The embedded PostgreSQL lifecycle module (embedded-lifecycle.ts) imports the
// `embedded-postgres` package, which uses dynamic import() for platform-
// specific optional binaries (@embedded-postgres/linux-x64, etc.). Re-exporting
// it from this barrel would pull those unresolved imports into every consumer
// of @fusion/core — including the CLI bundle (tsup/esbuild bundles @fusion/*
// with noExternal), which breaks the build and the boot smoke on platforms
// whose optional binary is absent.
//
// The embedded lifecycle is therefore NOT re-exported here. The runtime
// startup factory (startup-factory.ts) loads it lazily via await import()
// only when FUSION_EMBEDDED_PG=1, and the integration tests import it
// directly from "./embedded-lifecycle.js". This keeps the embedded-postgres
// dependency out of the static import graph of every other consumer.
