/**
 * `nexus db sql | status | migrate`.
 *
 * `sql` prints the Postgres schema, so the CLI needs no driver and the schema can go through the
 * application's own review and tooling: `nexus db sql | psql "$URL"`. `status` and `migrate` reach
 * the database through a module the application writes, which exports its own client:
 *
 * ```js
 * // db.mjs
 * import pg from 'pg';
 * export const client = new pg.Pool({ connectionString: process.env.DATABASE_URL });
 * export const close = () => client.end();
 * ```
 *
 * The module may also export `dialect` (`postgres` or `sqlite`), a `transaction` function (see
 * `PostgresMigrateOptions`), and `migrations`, a list replacing the bundled ones, for stores on
 * custom tables.
