I am using windows 8.
My Postgres was Correct.
I just took the data directory from C:/postgresql/8.3/
Now database was connected through command prompt.
When I was trying to connect using pgadmin, it's saying
FATEL: error
An error has occured:
Error connecting to sthe server: FATAL: role "postgres" is not permitted to log in
I changed the required things in pg_hba.conf (trust) and postgresql.conf (connection *) (port 5433)
But, still I was unable to connect the database.
How to give the permissions to postgres role.
when am trying to give the permissions through cmd also it's giving same error.
I was tried in so many ways
but, still I didn't get the database.
It looks like you might have accidentally revoked the LOGIN and SUPERUSER rights from the postgres user. Perhaps you created a superuser with a different name instead? Log in as that user if you did.
If not, and you can't get access as user postgres, you will need to start the database engine up in single-user mode and manually GRANT the SUPERUSER right to postgres again. This is much the same process as is required when recovering from a dropped (deleted) superuser account.

Postgres reset password in PostgreSQL server 8.4
BTW, 8.3 is a very old and unsupported version. Plan your upgrade promptly.
If there's no data in PostgreSQL that you care about, the easiest thing to do will be:
Uninstall PostgreSQL 8.3;
Delete C:\Program Files\PostgreSQL\8.3 (permanently and unrecoverably destroying all data in your PostgreSQL databases); and
Install a current PostgreSQL version

I'm trying to connect to employee.fdb in Firebird3.0 (localhost) using FlameRobin 0.9.3 on a Ubuntu OS.
The connection to Firebird using isql has no issues. I can create users, roles, etc all from the terminal. However, when I attempt to make a connection using FlameRobin I receive a 335544344 "Error while trying to open file Permission denied" response.
This occurs with the SYSDBA profile and any other new user profiles that I create in isql. I can even create new users in FlameRobin but I cannot connect to any database. I've verified in /etc/firebird/3.0/firebird.conf that DatabaseAccess = Full and have attempted to access the db from a couple different folders in case this is a read/write issue. No success.
I feel like I'm missing something obvious. Any thoughts?
Added info in response to Mark (4/26):
The db is stored in /var/lib/firebird/3.0/data/. I have assumed this to be the default location for Firebird DBs and that the server automatically has access to it, but I suppose that might not be the case. Is there a way to confirm server permissions to this directory and/or is this the customary spot to store work?
Terminal Connection with ISQL:
daniel#daniel-desktop:~$ isql-fb
Use CONNECT or CREATE DATABASE to specify a database
SQL> connect '/var/lib/firebird/3.0/data/employee.fdb' user sysdba password 'xxxxxxx';
Database: '/var/lib/firebird/3.0/data/employee.fdb', User: SYSDBA
SQL>
FlameRobin Database Registration Info:
FlameRobin Error:
This is a permissions issue as #MarkRotteveel suggested. Problem was that I installed the server as a user and not as root. Problem solved by removing and reinstalling both Firebird and FlameRobin as root.
I have just installed Postgres 12 on a Mac. As you may soon appreciate I am totally new to it.
During the installation process I was asked to provide a "password". I do not remember specifically, but I think it was for the some sort of admin role.
Now I want to create my first database. Reading the documentation I insert the command
createdb myfistdb
the system asks for a password. I give the one I set during the installation processes but I got the following error
createdb: error: could not connect to database template1: FATAL: password authentication failed for user "myusername"
where myusername is the user I am logged in.
The same happens if I give the system password of myusername.
I understand that my question is pretty basic, but I have been struggling quite some time without any success, so any help will be appreciated.
The database uset name used by createdb defaults to the operating system user name, so you'll have to specify the administrative superuser explicitly:
createdb -U postgres myfistdb

psql: FATAL: role "postgres" does not exist
(32 answers)
Closed 20 days ago.
I'm setting up Postgresql for use with a Rails app, but I do not seem to be able to connect to, or properly configure, the database (the errors I get after starting the Rails server are: ActiveRecord::NoDatabaseError and could not translate host name "MyProfile" to address: nodename nor servname provided, or not known).
I gather from the dozens of other questions on this topic that I need to switch to, or create the "MyComputer" role, however I've noticed that they all require using the psql command. When I run even just psql I, again, get the error FATAL: role "MyProfile" does not exist.
So far I've been following Heroku's instal process and am stuck here (or more accurately here, after the installation, where Heroku says that running psql -h localhost should work). Am I missing an obvious step here/doing something wrong?
I've also tried:
sudo su - MyProfile
variations of sudo -u postgres createuser owning_user
and a couple other commands in an effort to create this roll/user, but I can't seem to get done what I need to to resolve the issue.
EDIT
I've also run ps aux | grep postgres and it looks like all the PID's that are associated with anything postgres are running under "MyProfile" (assuming I'm reading it right). But the psql command still returns that the role does not exist. #sadface
EDIT 2
I just opened the Postgres App and clicked the "Open psql" button. It opened the Terminal, ran a command ('/Applications/Postgres.app/Contents/Versions/9.5/bin'/psql -p5432) and then gave me the same error (psql: FATAL: role "MyProfile" does not exist). Which perhaps suggests to me that it's an system issue, and not a Rails issue at all?
Edit 3
This is most certainly a pg issue, not a rails issue. I just uninstalled the app, reinstalled it using SQLite (yucks), ran the local server and got the test landing page to show up. So the problem appears to be with my local machine but not the app itself. Removed RoR tag, and still looking for answers from Postgres gurus on why the role issue persists :)
I ran into similar issues when setting a new Rails application with Postgresql. I got the following error messages below
FATAL: role "promisepreston" does not exist
Couldn't create 'MyBlog_development' database. Please check your configuration.
rails aborted!
ActiveRecord::NoDatabaseError: FATAL: role
Caused by:
PG::ConnectionBad: FATAL: role "promisepreston" does not exist
To solve this simply follow the solution below
First, we need to login to the postgres user account via the command line interface;
sudo su - postgres
Next, connect to the database server using the psql client, as the postgres role:
psql -U postgres
Welcome to psql 10.6, the PostgreSQL interactive terminal.
postgres#Preston-PC:~$ psql -U postgres
psql (10.6 (Ubuntu 10.6-0ubuntu0.18.04.1))
Type "help" for help
postgres=#
Next, connected with the psql client, we’ll create a role with our desired rolename that has the LOGIN attribute and our desired password, and that can create databases and manage roles (N/B: Please do not type this postgres=#, since it's a placeholder):
postgres=# create role rolename with createdb login password 'password1';
Note the required trailing semicolon ( ; ) at the end of the SQL statement. The single-quotes ( ‘ ‘ ) are not part of the password, but must enclose it.
Did it work? You can check using \du command (N/B: Please do not type this postgres=#, since it's a placeholder):
postgres=# \du
You can now run the command to create the database for your Rails application;
rails db:create
And then also run the command to migrate the database for your Rails application;
rails db:migrate
That's all.
I hope this helps
What a mess...one thing that I forgot to mention that probably would have been astronomically helpful to the community is that I'm taking over someone else's machine. There were lingering settings that just decided they weren't going to play nice.
At the end of the day, I got rid of Postgress.app, installed postgres with Homebrew, and the balance of what I needed was here: http://exponential.io/blog/2015/02/21/install-postgresql-on-mac-os-x-via-brew/
Specifically the line that saved me was createdb 'whoami' (see the actual post...the syntax is a bit different than what I just wrote because of stackoverflow formatting)...in retrospect it seems obvious, but it helped my current logged in user overcome the presets of the other legacy user by actually creating the database that the psql the whole setup was looking for.
Lesson learned!
Thanks for the help #max, helped me avoid another issue I was about to cause as well!
If you are using Postgres.app you should leave out the username and password from config/database.yml. Also that error is telling you that you have entered MyProfile not as the user for (or role in PG parlance) but as the host for the database connection (instead of localhost).
This is really all you need in your config/database.yml to get Postgres.app running:
default: &default
adapter: postgresql
encoding: unicode
# For details on connection pooling, see rails configuration guide
# http://guides.rubyonrails.org/configuring.html#database-pooling
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
development:
<<: *default
database: myapp_development
test:
<<: *default
database: myapp_test
Its often a good idea to leave it stripped down and let the fool who absolutely has to have a password on his dev postgres server use the DATABASE_URL env var.
I need to run multiple commands on an AWS Postgres RDS instance I have. I don't want to enter the password each time. I'm trying to use the .pgpass file but I'm running into errors. The first time I ran into an error which said 'role "ubuntu username" does not exist'. I logged in as the postgres user and created that username. After this, the error I get said database does not exist. I have a feeling these errors have nothing to do with trying to connect to the AWS RDS instance.
psql --host=<awshost> --port=5432 --username=<awsrdsusername> --password --dbname=<dbname asks for a password and then logs me in after I enter it. Now I put a file in /home/<ubuntuusername> called .pgpass which has <awshost>:5432:<dbname>:<awsrdsusername>:<password>. Permissions for this file are set to 0600. Now when I run psql from the terminal and that produces the error - psql: FATAL: role "<ubuntuusername>" does not exist. These steps are as outlined on this page.
Can someone help me with the steps to get a pgpass file to connect to an AWS RDS instance?
.pgpass doesn't provide connection information. You seem to expect that after you create a .pgpass file, you can run psql without arguments and it'll know where to connect. That is not the case.
The hostname, port, etc you put in .pgpass are there so that PostgreSQL knows which line to look at when matching the connection info to find its password.
If you had to run:
psql -h something
to connect without a .pgpass file, you still have to run the same thing to connect with a .pgpass file.
If you run psql without arguments it'll connect to the local PostgreSQL (if any), using the current unix username as the postgresql username and the database to connect to. That's why you get the error you do.
If you want to change the default connection, you can use environment variables like PGHOST, PGPORT, etc, and/or a .pgservice.conf file.

I need to do a report in JasperReports.... besides the point here.
Ive been given a existing Postgresql DB to use.
I have installed PostgreSQL and all went great. (except the package update at the end. Cant get past the proxy server)
Ive added the C:\Program Files\PostgreSQL\9.0\bin path the the system path as-well.
When I go to cmd and type psql it propts for a password....
I enter password, because thats the only password I added during instalation.
Then is comes up with psql: FATAL: database "Morne Nel" does not exist
step by step hoe do I import this DB into postgres? PLEASE?
When using psql you have to pass database name, otherwise postgres will try to connect to database matching your user name (that is why it tries to connect to "Morne Nel").
You can use createdb console command to create database first. Here is documentation on that command: http://www.postgresql.org/docs/9.3/static/sql-createdatabase.html
But also you can use pg_restore command right away with --create option passed to create and restore database from dump at once (documentation here: http://www.postgresql.org/docs/9.3/static/app-pgrestore.html).
Try to execute those commands (it is possible that you will have to specify your postgres user and password) and let us know what happened. I cannot write more at the moment as I am not sure what dump format do you have so it would be good to provide that information if you won't manage to use pg_restore successfully.
