I'm trying to connect to a postgresql database which is in localhost:5432 but I keep getting the error:
FATAL: Ident authentication failed for user "".
I installed Postgres11 on virtual machine running Centos7. Created a database through command line, with the name business_db.
I've checked and postgresql is running in localhost:5432.
My pg_hba.conf file is like this:
# TYPE DATABASE USER ADDRESS METHOD
local all all peer
host all all 127.0.0.1/32 ident
host all all ::1/128 ident
local replication all peer
host replication all 127.0.0.1/32 ident
host replication all ::1/128 ident
The pg_ident.conf file doesn't hold any configurations:
# Put your actual configuration here
# ----------------------------------
# MAPNAME SYSTEM-USERNAME PG-USERNAME
The database exists as shown by the command:
I'm logged into the system as "dev" user but., whatever I try while testing connection whit DBeaver, I allways get the error:
I also tried to set User as postgres and use my system password but get the same error. What am I missing?
When you use JDBC, you have to use password authentication. Neither ident nor peer will work for that.
You will need to add, e.g.:
host all all 127.0.0.1/32 md5
at the top of your pb_hba.conf
(replace md5 with scram-sha-256 if you are using that)
Change the ident to trust if you don't want to enter a password or to md5 if you want to enter a password.
Then reload the PostgreSQL server.
In (Ubuntu OS), change (or set) password in this way to solve this problem:
1- In terminal, run this command:
sudo -u postgres psql template1
2- Then run this command:
ALTER USER postgres with encrypted password 'your_password';
remove any spaces from your password, this worked for me

I'm a noob in PostgreSQL. I installed ver 9.2 on windows7. During installation it asked for password and i entered it.
Now whenever i run d:\tools\PostgreSQL9.2\bin\psql.exe it asks for password. When i enter the password it doesn't accept and
it shows "password authentication failed for user "user1". I have re-installed twice already. Also i tried entering my system
password.
I'm trying to get the below command to work
psql.exe -f db/codedb.sql development
What should i do to get this working ?
Try setting the user name when connecting.
psql.exe -U username -d dbname -f somefile.sql
You've probably set up the default "postgres" user during installation. Not sure if you've created any others.
To add other users and databases just connect to as postgres to the postgres database and do something like:
CREATE USER myuser WITH ENCRYPTED PASSWORD 'secret';
CREATE DATABASE mydb OWNER myuser;
If your machine is secure you might also like to set up a password file
change "trust" instead of "md5" in the pg_hba.conf to connect to the database and change your password.
--------------------configuration in pg_hba.conf---------------
local all all trust
local all postgres trust
host all all ::1/128 trust
Here is the simple solution for installation Postgresql without getting errors(cluster errors and authentication errors),i have followed below steps and i got installed postgresql sucessfully
create new user in windows from controlpanel-->user accounts
After logged into new user(whic u hve created) copy postrgresql(.exe) application into any directory(other than 'C') and click on the application to install(dont forget to change the installation directory to which u have copied the application file above).
after completion of installaion change below configurations in postgresql.conf and pg_hba.cof
add like below in your postgresql.conf
listen_addresses = '*'
add like below in your pg_hba.cof
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
# host sameuser postgres 127.0.0.1/32 trust
#host replication postgres ::1/128 md5
I am having an issue where I forgot the password to the postgres shell when trying to login as postgres. I looked online and found several different things to do, but none of it worked. I have messed with the pg_hba.conf file but even with that change, it is not working. Here is what my pg_hba.conf file looks like.
# Put your actual configuration here
# ----------------------------------
#
# If you want to allow non-local connections, you need to add more
# "host" records. In that case you will also need to make PostgreSQL
# listen on a non-local interface via the listen_addresses
# configuration parameter, or via the -i or -h command line switches.
# CAUTION: Configuring the system for local "trust" authentication
# allows any local user to connect as any PostgreSQL user, including
# the database superuser. If you do not trust all your local users,
# use another authentication method.
# 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
# Allow replication connections from localhost, by a user with the
# replication privilege.
host replication all 127.0.0.1/32 trust
host replication all ::1/128 trust
and then i ran the follwoing command:
brew services restart postgres
and I keep getting the following error:
omars-MacBook-Pro:postgres omarjandali$ psql -U postgres Password for user postgres: psql: error: could not connect to server: FATAL: password authentication failed for user "postgres"
Anyone know how to fix this issue.
It looks like your command psql -U postgres is attempting to make a socket connection, however you've only got trust authentication set up for TCP/IP connections on localhost.
Try psql -h localhost -U postgres.
Alternatively, add a line to pg_hba.conf setting up trust authentication for socket connections:
host all all trust
and restart PostgreSQL (though you don't actually need to restart it, pg_ctl -D /path/to/data-directory reload should work if you know the actual data directory path).
I'm completely unable to access anything in postgres as it's asking for a password for both the default postgres user as well as my mac username. I don't have a password for either, and in the case of postgres I don't even understand why there is a password as by defualt it shouldn't have one.
After running through many other answers on the subject:
If I run psql:
$ psql
Password for user <MY_USERNAME>:
psql: error: could not connect to server: FATAL: password authentication failed for user "<MY_USERNAME>"
If I run it with sudo:
$ sudo psql
Password for user root:
psql: error: could not connect to server: FATAL: password authentication failed for user "root"
If I run it with postgres user:
$ sudo -u postgres psql
Password for user postgres:
psql: error: could not connect to server: FATAL: password authentication failed for user "postgres"
Also in my pg_hba.conf all the methods are set to trust, have also tried changing to ident and md5.
On the advice of #jjanes I searched for other pg_hba.conf files and this is what I found:
/usr/local/var/postgres.old/pg_hba.conf
/usr/local/var/postgres/pg_hba.conf
/usr/local/var/postgresql#10/pg_hba.conf
/Library/PostgreSQL/12/data/pg_hba.conf
The last one is empty (and read only) and the other three all look like this:
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
local replication all trust
host replication all 127.0.0.1/32 trust
host replication all ::1/128 trust
Anyone have any advice?
I had a similar issue on my Ubuntu 21.10.
I also tried resolving the problem by following the steps suggested above, but none worked.
At last, I resolved the problem by uninstalling postgres and removing every related files: https://askubuntu.com/questions/32730/how-to-remove-postgres-from-my-installation/32735#32735
Thereafter, I did a new installation of postgres using: https://levelup.gitconnected.com/installing-and-configuring-postgresql-on-ubuntu-20-04-e50122635927
Now, everything works fine.
Cheers.
I'm pulling my hair out trying to figure out what is wrong.
I am attempting to connect to a local install of postgres 11 on ubuntu 19.
sudo -u postgres psql gives me full access to the psql shell as user postgres. I created a new user and db, granted permissions, set a password, edited the pg_hba.conf file, and restarted the server. I have also ensured that my password is not expired.
Now I expect psql "host=localhost user=marcos port=5433 dbname=reddit sslmode=require" to connect to my database, but I get a password error: "psql: FATAL: password authentication failed for user". I know the password I typed is correct, so what is wrong?
Here are the relevant pg_hba.conf lines:
# Database administrative login by Unix domain socket
local all postgres peer
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all md5
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
local replication all peer
host replication all 127.0.0.1/32 md5
host replication all ::1/128 md5
# custom rules
host all marcos all md5
follow this step for ubuntu/linxs
-> sudo -u postgres psql
-> postgres=#
After that right
->postgres=# \password
Enter new password for user “postgres”:
Enter it again:
Now check, the new password is working successfully.
Maybe something is wrong with your old password, try this:
ALTER ROLE marcos WITH ENCRYPTED PASSWORD '<new_password>';
And then connect to your DB with this password.
I'm a noob in PostgreSQL. I installed ver 9.2 on windows7. During installation it asked for password and i entered it.

Try setting the user name when connecting.
