FATAL: password authentication for user

I am having a problem connecting my postgres database. I created a user for him (he never asked me for a password), so I created the ALTER USER user_name WITH PASSWORD password command to create it. I set the user and password in my database.yml file in my configuration directory for my Rails project. He still tells me that I have an authentication error (like my header), 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 would solve this problem is to make my user superuser. But I would like to know why this is not working right now, without making it superuser. Does anyone have an idea?

  • will make you a superuser: ALTER USER user_name WITH SUPERUSER;

  • edit the pg_hba.conf file: set the method from md5 to trust

USER METHOD DATABASE TYPE

IPv4 local connections: host all all 127.0.0.1/32 trust

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

.................................................. .............................

In my case, I found that the later line of the host permission rule in the pg_hba.conf exceeded the previous local line. I correctly configured the local string to use md5 authentication, but the host string was set to ident , which I changed to md5

Note that using trust is an unsafe method, so you should not use it in any production-style deployment.
