Postgres Deno Connection Pool Idle timeout

I am using NeonPostgres and connecting to the database in Deno using the following below and executing this way. This connection is running in a Discord bot using Discordeno. I am entirely ruling out local network setup however the discord bot itself never disconnects. So that brings me here. After a certain time frame that I haven't determined quite yet. Maybe 20 minutes or so?

import { Pool } from "https://deno.land/x/postgres@v0.19.3/mod.ts";

const pool = new Pool({
  database: Deno.env.get("POSTGRES_DATABASE"),
  hostname: Deno.env.get("POSTGRES_HOST"),
  port: 5432,
  user: Deno.env.get("POSTGRES_USER"),
  password: Deno.env.get("POSTGRES_PASSWORD"),
  connection: {
    attempts: 10,
  },
  options: {
    
  }
}, 10);
export { pool };

import { QueryArrayResult } from "https://deno.land/x/postgres@v0.19.3/mod.ts";
import { pool } from "../database/database.ts";

export class ChatMessageRepository {

    public static async getChatMessagesByChannelIdAndUserId(channelId: bigint, userId: bigint): Promise<QueryArrayResult<unknown[]>> {
        const client = await pool.connect();
        const chatMesages = await client.queryArray(
            `SELECT "Content", "IsBot" FROM public."ChatMessages" WHERE "ChannelId" = ${channelId} AND "UserId" = ${userId} ORDER BY "CreatedAt" ASC;`,
          );
        client.release();
        return chatMesages;
    }
}

import { Pool } from "https://deno.land/x/postgres@v0.19.3/mod.ts";

const pool = new Pool({
  database: Deno.env.get("POSTGRES_DATABASE"),
  hostname: Deno.env.get("POSTGRES_HOST"),

            `SELECT "Content", "IsBot" FROM public."ChatMessages" WHERE "ChannelId" = ${channelId} AND "UserId" = ${userId} ORDER BY "CreatedAt" ASC;`,
          );
        client.release();
        return chatMesages;
    }
}

ConnectionError: The session was terminated unexpectedly
0|chatbot  |       throw new ConnectionError("The session was terminated unexpectedly");

Deno Bindgen

When attempting to follow the deno bindgen documentation I get errors about not being able to parse the cargo output or not being able to find symbols, I am basically following the example folder in the repo.
Is the deno_bindgen project ment to be installed locally as a cargo crate for the project so you can annotate the functions with deno_bindgen? Am I missing something in the documentation? If someone is knowledable about the crate I can post more error information.

Deno_bindgen

I'm super happy to see the Deno NPM compatibility supporting an FFI call using Rust's NAPI crate for a npm package I just made. I'd like to make a first class Deno TPM, is deno_bindgen ment to be installed as a crate within the FFI binding project or cloned and have the binding code moved into the cloned repo? The first seems more logical for me but I had some problems just executing simple binding generation. I can post a more specific error if its needed.
