Problem with extended SapphireClient

import { SapphireClient } from "@sapphire/framework";
import { container } from "@sapphire/pieces";
import type { ClientOptions } from "discord.js";
import { drizzle } from "drizzle-orm/node-postgres";
import pg from "pg";
import { dbConnectionString } from "../config.js";

const { Client } = pg;

// @ts-expect-error Somehow errored with d.js ClientOptions conflict
export class BotClient extends SapphireClient {
    public readonly db = drizzle(new Client({
        connectionString: dbConnectionString
    }));

    public constructor(public readonly options: ClientOptions) {
        super(options);

        Object.assign(container, { db: this.db });
    }
}

declare module "@sapphire/framework" {
    type SapphireClient = {
        readonly db: BotClient["db"];
    };
}

declare module "@sapphire/pieces" {
    // eslint-disable-next-line @typescript-eslint/consistent-type-definitions

        readonly db: BotClient["db"];

}

const client = new BotClient({

    intents: ["Guilds"]

});

client.on("ready", () => {
    console.log(`Logged in as ${client.user?.tag}!`);
});

await client.login();
