Can you try another region? I had issues where the Postgres DB wasn’t being stood up before the deployment finished. I’m not at my computer but if you pasted clean logs (there is potentially some PII depending on how far back your logs go) I can point to the spot you should see it set up correctly.

Basically there should be output showing the Postgres credentials and the full url right after it starts provisioning the database. If you’re not seeing that in the logs then I suspect you’re running into what I did. I solved my problem by switching to the Miami region from Virginia. It’s possible this is a problem in only the one region or I had issues I could troubleshoot my way out of. The fact that it worked seamlessly in another region kinda suggests otherwise.
