/**
 * PostgresAdapter — stub for batch 5 of the DB migration.
 *
 * The real implementation uses `pg` (added to package.json in batch 6)
 * and wires up the schema_migrations bookkeeping table. Until then this
 * stub keeps the module graph type-correct so the Next.js build passes;
 * constructing it throws at runtime, but nothing in the app calls
 * getDbAdapter() yet — the legacy lib/db.ts path is still authoritative.
