I have configured pgbouncer on server A(port 6432, host addr: 10.XX.XX.92) that will accept the connections for postgres server running on server B(port 5433, host addr:10.XX.XX.90). This postgres server has 2 databases.(postgres and db1)
I have 2 different type of users(user1, user2) that will connect to same database(db1). These both users have different set of permissions on db1.
Below is the sample of how I have configured pgbouncer.ini file.
database1 = host=10.XX.XX.90 port=5433 user=user1 password='pwd1' dbname=db1
database2 = host=10.XX.XX.90 port=5433 user=user2 password='pwd2' dbname=db1
Now when I try to connect to this database through pgAdmin it gives me an error of "No such database" .
Below are the connection variables that I used to connect through pgadmin for user1.
host = 10.XX.XX.92
port = 6432
maintenance database = database1
username = user1
password = pwd1
But when I use same variables and try to connect using DBeaver or psql, I am able to connect to the database db1 successfully.
Does anyone know if this is just pgAdmin issue or am I missing something here.
Note: There is one more thing I tried. If in the pgbouncer.ini, I name the database variable(database1) same as actual database name(db1), pg
Admin lets me connect to the database. This would have worked for me if I just had one user connecting to the database but I have two users and they both can't have same connection name in the config file.
Have a try here :

add this to your connection string :
EntityAdminDatabase=DATABASE_NAME

I am following a tutorial on how to create a to do app with PERN stack.
(working on ubuntu 18.4, postgres version 12.3)
I did install the PostrgreSQL, server is running on 5000 and I am able to enter to the database from the command line with "psql -U postgres" but when I try to connect database with the server I am getting this error: password authentication failed for user "postgres".
I was not asked to give any password to the user "postgres" while instalation so I left the password in the db file empty.
My db file looks like this:
const Pool = require("pg").Pool;
const pool = new Pool({
user: "postgres",
password: "",
host: "localhost",
port: 5432,
database: "perntodo",
});
module.exports = pool;
what can I co?
I did set the postrgres authentication in pg_hba.conf file from peer to trust as I found in another issue on stockoverflow, but the error keeps appearing.
The immediate fix would be to eliminate:
host: "localhost"
from your connection settings. This would force the connection to be made on local which would be equivalent to what you are doing with psql -U postgres.
The longer term fix would be to use psql -U postgres to connect and then ALTER ROLE postgres WITH PASSWORD '<some_pwd>'. This would give this ROLE a password. You can do this with other roles that already exist by using ALTER or when you CREATE a new role in the create statement.
The connection authentication methods are controlled by the pg_hba.conf file. A full explanation of what it does is available here:
https://www.postgresql.org/docs/current/auth-pg-hba-conf.html
If the above does not answer all your questions then come back with specific concerns.
Don't use user postgres to connect your application to PostgreSQL.
Create separate user for application.
Grant to application user strict permissions only for schemes and tables what it need access.
Add pg_hba.conf record for application user
Enjoy
If I go as per your error message, then you need to reset postgres password. And I believe the default isnt working or you might have forgotten after resetting it.
Please follow below tutorial for resetting password:-
https://docs.bitnami.com/aws/infrastructure/postgresql/administration/change-reset-password/
or refer the answer for below:-
What is the default password for Postgres
I created a database using the GUI of pgadmin and it works well. I can connect to the server with my password. But when I want to connect to the database using psql in terminal, after I enter the password, it says
psql: FATAL: password authentication failed for user "{username}"
I tried every possible password, but it's still not working.
Has anyone meet this issue before?
I'm a newbie to PostgreSQL and I'm trying to create a user/role on Postgres 11 (running on CentOS7) which is named (e.g.) "json_docs_admin" (same for password) that I can use under the OS user (e.g.) "app_user" to connect locally to the DB.
I have tried connecting to Postgres using "postgres" user and the command "psql -d template1" and ran the following commands:
template1=# create role json_docs_admin with login password 'json_docs_admin';
CREATE ROLE
template1=# create database json_docs owner=json_docs_admin;
CREATE DATABASE
template1=# GRANT ALL PRIVILEGES ON DATABASE json_docs TO json_docs_admin;
GRANT
I have changed the /var/lib/pgsql/11/data/pg_hba.conf so that local connections can be established on the server, and I've restarted the postgresql service.
Then, back under "app_user" user, when I try to connect to the database, I get the following errors:
$psql -d json_docs -U json_docs_admin
Password for user json_docs_admin:
psql: FATAL: database "json_docs" does not exist
Could anybody let me know what am I doing wrong?
Thanks.
I am connecting postgres database with wrong password and connection string and user role is correct and still i am able to connect the database?
How its possible?
when you are connecting with database there is a situation when postgres does not ask for password
1. when you are installing the postgres and creating localhost server first time and making connection without password than it needs only the correct following :-
1. username or userrole
2. correct connection string

Hello i am a beginner to postgresql, I am unable to connect Postgresql database on linux system from windows through pgadmin client . I am getting the following error
FATAL: no pg_hba.conf entry for host "192.168.1.42", user "postgres", database "postgres", SSL off
Kindly suggest me how to do.Thanks in advance
On the db server, edit your pg_hba.conf file and add a line similar to this:
host all all 192.168.1.42/32 md5
If you don't want to use a password (I won't get into the security aspects), you can switch the "md5" for "trust". If you only want to allow the postgres user access to the postgres maintenance database, then switch both "all" words with "postgres" (no quotes).
You'll need to reload the config files after making any changes.
Eg.
pg_ctl reload
or
select pg_reload_conf(); -- as the superuser
If you don't know which pg_hba.conf file your database cluster is using, if you can connect to any of the databases, issue select current_setting('hba_file');
by default, postgresql deny all connexion if it's not from "localhost"
