I’m having issues with creating a backup from the admin section, running discourse from the docker container on localhost.
The error I’m getting is:
`pg_dump: error: connection to database "discourse development" failed: FATAL: Peer authentication failed for user "postgres".`
I checked the pg\_hba.conf file, and have all options set to trust.
Would be great if I could get some assistance on how to get this to work.
I tried on Ubuntu as well as on MacOSX. Everything else from the discourse instance is working fine on both (creating Posts, API…) except for the backup functionality.

That could be a regression. It should be using user discourse, I’d think.

Where could I change the user being used by discourse?

How did you install?

Following this tutorial:
> [@Install Discourse for development using Docker](https://meta.discourse.org/t/beginners-guide-to-install-discourse-for-development-using-docker/102009):
>
> Developing using Docker Since Discourse runs in Docker, you should be able to run Discourse directly from your source directory using a Discourse development container. white_check_mark Pros: No need to install any system dependencies, no configuration needed at all for setting up a development environment quickly. x Cons: Will be slightly slower than the native dev environment on Ubuntu, and much slower than a native install on MacOS. See also [Developing Discourse using a Dev Container](https://meta.discourse.org/t/developing-discourse-using-a-dev-container/336366) …
As I said, everything works fine, except for the backup.

Hi Max! Were you able to fix this issue?
I’m currently having the exact same problem, although I first detected it trying to make a restore on my local docker development install.

Hi @max-elia I’ve also run into this problem, were you able to get it fixed by any chance?

I fixed it by adding username: discourse directly into my database.yml. Thank you!

where in the file did you add it and what else did you do?? Adding it to the development section and simply restarting (`d/shutdown_dev; d/boot_dev`) didn’t do it for me.

Right under `adapter: postgresql` in the config/database.yml Then I followed the `script/discourse restore ` Which was what I was trying to accomplish.
