Backup fails on localhost with docker

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?

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 <filename.of.the.backup.tar.gz> Which was what I was trying to accomplish.
