Can't use legacy db._query on drizzle beta version

import type { Logger } from 'drizzle-orm';
import { defineRelations } from 'drizzle-orm';
import { drizzle } from 'drizzle-orm/postgres-js';
import postgres from 'postgres';

import * as model from './model';

const relations = defineRelations(model, (r) => ({
  users: {
    customers: r.many.customers(),
    company: r.one.companies({
      from: r.users.companyId,
      to: r.companies.id,
    }),
  },
 ....
}));

const client = postgres(process.env.DATABASE_URL!);

export const db = drizzle({
  client,
  casing: 'snake_case',
  relations,
});

export * from 'drizzle-orm';
