Docs unclear on connection pool vs. direct connection

In the docs under "Supabase" it teaches you how to setup Drizzle w/ supabase. The last part shows how to set up the connection:

import { drizzle } from 'drizzle-orm/postgres-js'
import postgres from 'postgres'
import { users } from './schema'
 
const connectionString = process.env.DATABASE_URL
const client = postgres(connectionString)
const db = drizzle(client);
 
const allUsers = await db.select().from(users);

import { drizzle } from 'drizzle-orm/postgres-js'
import postgres from 'postgres'
import { users } from './schema'
 
const connectionString = process.env.DATABASE_URL
const client = postgres(connectionString)
const db = drizzle(client);
 
const allUsers = await db.select().from(users);

But underneath it simply says: Connect to your database using the Connection Pooler for serverless environments, and the Direct Connection for long-running servers. I'm assuming the code above is for Direct Connection? If that is the case, why is there no implementation demonstration for the Connection Pooler? Also isn't Supabase always going to be serverless? Maybe I'm missing something but this just feels confusing

I guess you're right. Would you like to open an issue in GitHub for this?

Sure I’ll do this In the meantime tho, how do you set up drizzle with serverless supabase?

Angelelz•16mo ago

Use a pool as it's recommended

Maybe I am dumb but I can't make pooler url working with Supabase. It always ends on errors when my code runs. Afaik, postgressjs handles pooler. You just have to choose the good connection string.

Read carefully if you use prepared statements, the default pool mode on Supabase is "transaction" and doesn't handle them.

Looks like a connection pooler is the way to go according to this Any luck resolving this?

I opened a ticket and no clear answer What happen to me: deploying 3 instances on fly.io (docker containers), few minutes later everything is done with cryptic errors related to pooler I chatted with someone with the same issue

Is the Drizzle team aware of this? I’m sure there are tons of ppl using Drizzle w serverless Postgres dbs so I’m guessing we’re just missing something?

This is at least a driver issue or a Supabase issue 🥶 Or this is just me 😂
