I am a student. I've created a Rails/React project using PostgreSQL. I downloaded DBeaver so that I can view my database but cannot get DBeaver to connect, and have spent a couple of hours trying to solve this.
I attempt to set up DBeaver for PostgreSQL, click "New Connection," leave all defaults set and click "Finish" when I'm met with the following error:
The server requested password-based authentication, but no password was provided.
I am pretty certain that I never entered a password for this database. I saw it suggested that the default password is "postgres" but I tried that with no success. In terminal when I run "psql --list" I can see my DB's name and I can see that I am the owner.
I am running a Debian distro, if that makes any difference. I installed DBrowser through Synaptic. I'd appreciate any assistance.

I am a new user of PostgreSQL, and I am learning it so that I can use it with Django, so I am trying to use the createdb command to create a new database, but even though I am entering the correct password for my account, I am getting this error. I reinstalled everything and checked everything I could think of but I was not able to solve this error. So, if I can get some help regarding this issue it would be nice.
Even using the command psql, and submitting the correct password, gives the same error.
I am using Windows 10.
As far as I checked, I needed to enter the password I used while installing PostgreSQL.
By the way, I am using the latest version of PostgreSQL 14.1
The command I used:
createdb testdatabase
createdb: error: connection to server at "localhost" (::1), port 5432 failed:
FATAL: password authentication failed for user "<username_placeholder>"
So, basically, I figured the solution myself. I am just posting it here because mostly answers are available for Linux and not Windows. So, if a windows user has a similar problem, maybe this answer could help them.
So, the first thing is, if you need to open psql, use the command:
psql -U postgres
and then enter the password you used while installing PostgreSQL. Now, if you wish to do something similar to what I tried, what I mean is to use createdb command in the terminal itself, then you will have to create a new user using the same username as you do for your PC, like in my case, it is aryan.
(For example: C:\Users\aryan\).
I followed instructions from this website.
I personally used pgAdmin 4 to do it, you could also use the SQL commands themselves.
After doing everything, when I used the createdb command directly from the terminal/powershell, it asked my the password which I had used to create the other user( with the same username as my system/pc) using pgAdmin 4. That's it. This helped me out.
I have browsed the web but didn't find any answers/solution to my problem, so i hope somebody here can help me:
I have downloaded DataGrip because i wanted to replace pgAdmin 4. When i try to create a PostgreSQL data source and host it locally, i get the following error: "Null value for 'password'". In pgAdmin 4 i do remember creating a password to access my local database when i first set it up, and it worked fine. However, i don't remember creating a password when installing DataGrip. Is there some default password that im not aware of? And what should be written under "User"?
DataGrip can only connect to the server which already exists (and therefore has a password). "Data source" is the term of DataGrip.
In other words, you need to already have a working database on the server with the known credentials.
As I attempt to create my initial user account on postgresql, I am prompted for my password, though when I enter the correct one I recieve:
createdb: could not connect to database template1: FATAL: password authentication failed for user "thomasmurphy"
I am installing through brew. My thought is that somewhere along the line I've set a password different from my system one. How do I remove all users so I can reset this pass.
I get my permission denied even if I su to postgres. I have gone through every thread on stackoverflow on this issue, and have tried:
*modifying my pg hba_conf
*updating my gems and developer tools
*running brew doctor
*reinstalling postgres
*all the other command line ideas through the thread
My situation seems to not have cropped up before, which convinces me I've set a password at some point that is now tripping all of my attempts. Adding to this theory is that I have a postgres setup on my work computer, also on mavericks, function perfectly.
Note that unless you changed defaults, homebrew installs Postgres with you as the superuser rather than as the postgres user. The issue might be that you're trying to use postgres "as normal" whereas it doesn't need or event want the usual postgres user references.
You see the list of users on the system using cat /etc/passwd, and you can change an arbitrary password by running chpass as root.
I'm trying to use postgresql with Rails so I can run locally before deploying to Heroku. I installed the latest version of postgresql (9.2.4) from enterprisedb.com.
When I try to double click the database in pgAdmin III, it asks for a postgresql password. There is no Windows postgresql account in the user settings. I did notice that during my subsequent uninstallation of the application, the uninstaller referenced a service user account "NetworkService."
If I try to run the command line psql command, it asks for a password, then it complains that authentication failed for (my windows login account name). I tried entering my usual Windows account password, and that didn't work.
What's going wrong here? I've read many posts of people running into password/account issues with this database.
There is no Windows postgresql account in the user settings.
The installer for 9.2 doesn't create a postgres Windows user account. People were having too many problems with the service account password, getting confused between the service account and the postgres database account, etc. It now installs and runs as NETWORKSERVICE by default.
You will have set a PostgreSQL database password when you installed. You must log in to PostgreSQL as the postgres user with the password you gave during installation.
With the help of bma, I was able to get my Rails application running on Windows by following these steps:
Install postgresql for Windows.
Open the pgAdmin III application from the Windows Start Menu.
Click on the File menu, click Open pg_hba.conf
Browse to C:\Program Files (x86)\PostgreSQL\9.2\data\pg_hba.conf.
Double click each of the rows and change md5 to trust
First, I'm a total newbie and I guess that's why this error occurred in the first place.
A colleague of mine stopped working and so I had to take over administrative stuff as the redmine we use and making backups.
So I wanted to schedule these backups automatically. Somewhere on the way I changed /etc/postgresql/9.1/main/pg_hba.conf for user postgres (that's the one for the redmine database.
from local all postgress peer to local all postgress trust so I could run a shell program in crontab. This worked but then redmine doesn't work anymore. I get this:
FATAL: password authentication failed for user "postgres" FATAL:
password authentication failed for user "postgres" (PG::Error)
On this the error site for redmine. I changed everything back and restarted everything, but it did't work.
Then I used an older backup to restore but still.
So, now I have no idea whats wrong. Maybe someone can help me.
Thanks.

I think it is because I've changed the password of the postgres user in ubuntu. I did not know at the moment that they are connected. I always got a password promt but I didn't know it (my colleague at least didn't tell me one) I've tried to change it in the data base as well with
ALTER USER Postgres WITH PASSWORD 'newpassword';
Would it be enough to reinstall the database and use an old backup?
