/**
 * PocketBase Compatibility Layer
 *
 * This module was originally written for PocketBase. After the migration to
 * PostgreSQL + Drizzle ORM (commit 7333548), all functions now delegate to
 * the new `database.ts` module which uses the Drizzle ORM with postgres-js.
 *
 * The naming is preserved for backward compatibility — ALL API route files
 * import from this module. Do not rename the exports unless you also update
 * every file that imports them.
 *
 * @see ./database.ts for the actual Drizzle ORM implementation.
