I'm having an issue connecting my Postgres database. I created a user for it (it never prompted me for a password), so I ran the command ALTER USER user_name WITH PASSWORD password to create one. I set the user and password in my database.yml file in my config directory for my Rails project. It's still telling me that I have an authentication failure (like my title) and I have no idea why. I modified my pg_hba.conf file from this answer from this link. The only thing I can think of that would solve this issue is making my user a superuser. But I'd like to know why this isn't working right now without making it a superuser. Anyone have any idea?

  • You are certain you are connecting as the user you think you are? What is the full ERROR message in the db log? Commented Aug 22, 2013 at 2:49

    Making your user a superuser won't help. The password is wrong. Check if you have a ".pgpass" file with a bad password. Commented Aug 22, 2013 at 6:53

  1. make you user superuser: ALTER USER user_name WITH SUPERUSER;

  2. edit the file pg_hba.conf : set method from md5 in trust

TYPE DATABASE USER ADDRESS METHOD

IPv4 local connections: host all all 127.0.0.1/32 trust

IPv6 local connections: host all all ::1/128 trust

Restart the server just in case: sudo service postgresql restart

I had this issue when working on a Rails application with PostgreSQL database.

The database user already had Super admin rights and permissions to the database that I created, but I was still encountering this error:

F, [2020-10-23T08:04:06.031161 #8902] FATAL -- : [4229b10c-e16f-4f26-90cc-facd47b2088c] ActionView::Template::Error (FATAL:  password authentication failed for user "prod_user"
FATAL:  password authentication failed for user "prod_user"

Here's how I fixed it:

The issue was that the Database Password for the prod_user specified for my Database environment variable was not correct in my .env file.

I had to modify it to into the correct one.

That's all.

I hope this helps

In my case, I found that a later host permissions rule line in the pg_hba.conf file had over-ridden the earlier local line. I was correctly configuring the local line to use md5 authentication but the host line was set to ident which I changed to md5

Note that using trust is an insecure method, so you shouldn't use it in any production-style deployment.

In my case, I was having this error because I was connecting to the wrong port (5432 instead of 5433).
