Node v17 ECONNREFUSED

Description

On node v16.13.0, connecting to the database works as expected. I decided to try out the changes in v17.0.1 and I can’t connect to the db anymore.

Test script:

import pg from 'pg';

export const pool = new pg.Pool({
    user: process.env.POSTGRES_USER,
    password: process.env.POSTGRES_PASS,
    database: 'kb'
});

console.log(process.version);
pool.query(`SELECT NOW()`).then(({ rows }) => console.log(rows[0]));

Output (both versions)

pg>node test
v16.13.0
{ now: 2021-10-29T18:14:27.011Z }
pg>node test
v17.0.1
node:internal/process/promises:246
          triggerUncaughtException(err, true /* fromPromise */);
          ^

Sorry, I’m not sure what the issue was anymore. I was able to upgrade later and everything is running on node 18. Usually we have node outside docker, directly on the mac host, and then postgres within docker. Maybe I posted the comment above when I was trying to run it within our CI or on macos, therefore completely in docker. I can report back here in case it’s still failing as I’ll upgrade to node 18 within the next 2 weeks.

@marcbachmann is your code running in a container and your DB running in another?
