I upgraded Discourse to latest stable version with complete rebuild yesterday. I’ve got this strange error this morning:

```plaintext

```

The postgresql 9.6 server is running outside the container and it’s accessible on port 5433. If I manually run the pg\_dump command inside the container then it works flawlessly and I haven’t detected any other DB related issue in Discourse.

Any idea why does it take wrong config settings? 😕

Thanks a lot!
