Thanks Patrick, looking at the package-lock.json diff, I only see sequelize going from^4.42.0 to ^4.44.3 but didn't touched pg at all. I don't have a lot of time to test this locally but should be able to repro locally assuming the local PG instance requires SSL. Unfortunately when using the default postgres Docker container and my code above I was getting this error:
SequelizeConnectionError: The server does not support SSL connections
Our cloud-based Postgres enforces SSL connections and that this was the only way I could get it to work. Thanks!
