I have tried the latest discourse with official Docker image few days, and I found the regular backup operation would be failed every time, the error log contains:

```plaintext
FATAL: Peer authentication failed for user "postgres"

```

When I typed this issue, I got few similar topic in the right, after I checked them I think this is still a new unfixed problem. And the solution comes from [here](https://stackoverflow.com/questions/18664074/getting-error-peer-authentication-failed-for-user-postgres-when-trying-to-ge), as current postgresql installed built in docker image, need change the configuration of postgresql like:

```plaintext
#TYPE DATABASE USER ADDRESS METHOD
local all all trust

```

So with this configuration the backup function would be work. I didn’t checked a lot in current issue list, if there is fix about it, please ignore this.
