I have a fresh install of a database on AWS. I have installed PG Admin 4 for Web and set up for a user login. This works.
I find it is not possible to connect to the localhost database using 'postgres' as a user, without a password. This appears to be enforced by the dialog. Is there a way around this enforcement? How would a user only having web access ALTER this ROLE? I would expect this to be relaxed for the initial login.
The database is local to the webserver and the web server is remote for the user.
TL:DR This logon is not a peer logon as the postgres *nix user.
It's a gap in the install. A manual step will always be required to add a password for postgres for anyone wanting to use the interface for initial USER/ROLE creation. It would be nice to have had this opportunity in the setup script.
I suppose it is expected that most administrators would also add other users/roles at this time and these would be supplied to the users. Changes to config files would still be managed. They are not getting shell access.
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 installed pgadmin4 on ubuntu 18.04 with the command:
sudo apt-get install pgadmin4 pgadmin4-apache2
During installation as usual I was prompted for an email and password, so I provided my email and a password. After installation when I try to login to pgadmin4 homepage with that email, I get the error:
specified user does not exist
I probably provided my email with some typo during installation. How do I solve this problem now? Is it possible to reset email without re-installing pgadmin4?
I found the db location where my credentials are stored.
var/lib/pgadmin/pgadmin4.db
In user table credentials are stored.
Funny thing is that postgres#localhost is appended right before my email. While providing email didn't expected them to be appended to my email address.
So to update my credentials I installed SQLite 3 and sqlitebrowser by following this tutorial.
I had to change permission of pgadmin folder and pgadmin4.db file. Rest was easy-
open sql browser
click on open database
click on browse data
select table user
update emeil address and save changes. Done
Here is the database I am trying to install (comes with 4 short instructions very easy to follow): https://github.com/toddwschneider/nyc-taxi-data
I used git clone to bring the repository down to my vm. And next I cd into it and run initialize_database.sh. Here is what happens:
pic of terminal
the password I am trying to use is the one provided by my Bitnami Launchpad, which says the admin user is postgres, but when I work on it it says kzherbert, my google account. I have tried su postgres but its not a user on the server so it doesnt work like that. I can use postgres password for psql -U postgres, which will take me to the psql terminal. Also, I have tried using my google account password as well and it does not work. What really interests me about the picture is where the shapefile is relevant and why it repeats and doesnt allow me to exit
Any and all help is greatly appreciated.
The problem is that the database you are trying to install (Unified New York City Taxi and Uber data) assumes you're installing PostreSQl from scratch instead of using the one included in the Bitnami Image.
The script you're using assumes that the user to connect the database is the same that the System User you're using to connect to your server via SSH (kzherbert in your case). However, the password you're trying to use is the one for the user postgres.
You need to connect to PG using the password Google provided you and the user postgres and the create an user kzherbert with the password you desire.
I have attempted to install PostgreSQL 9.4 and 8.4 multiple times and it is failing no matter what I have tried. I am attempting to install on Windows 7 SP1 x64. After each failed install I have uninstalled and deleted the installation folder to start fresh.
Each time I attempt the install I get an error pop up near the end of installation that says:
"failed to load sql modules into the database cluster".
Then another error pop up displays immediately after that says:
"Error running post install step. Installation may not complete correctly. Error reading C:/Program Files/PostgreSQL/9.4/postgresql.conf"
I have attempted installation with the following actions:
Always installed as administrator
Turned off all virus protection and windows firewall
Changed the installation directory to something other than the Program Files directory.
Changed the data directory to something other than the installation directory of postgres
None of the actions above have helped and I always receive the error. Any help that someone can provide would be greatly appreciated!
Encountered a very similar problem that OP is reporting today while installing Postgres 9.4.
It turns out that the password generator I was using has made a password that contains non-alphanumeric characters. ("^") I believe was the culprit in this case. Removing that allowed the installation of Postgres 9.4 (Windows 64 bit) to complete.
Very easy fix once you've found it, but the error message that comes up is not descriptive, so in this case I didn't notice at first what I was doing wrong.
I was getting this same error when trying to install PostgreSQL v9.4.4 on Windows 10 Pro. Starting with a solution hosted on Stack Exchange, I came up with the following steps that allowed the installer to run successfully:
1) Create a new user account, called postgres
2) Add the new account to the Administrators and Power Users groups
3) Restart the computer
NOTE: I added step #3, since step #4 didn't work without it
4) Run a command prompt as the postgres user, using the command:
runas /user:postgres cmd.exe
5) Run the installer from the postgres command window
6) Delete the postgres user account, as well as the user directory
NOTE: I added step #6, since the postgres account is not required after installation
What worked for me is, during the install, specifying a Postgre SQL data folder that's outside of any Windows user profile directory (C:\Users), such as C:\postgres-data.
My setup:
Win 10 Pro
PostgreSQL 9.5 RC1
I ran into this issue when I tried setting PostgreSQL's data directory somewhere under my user profile's directory, such us somewhere under "My Documents".
I tried Jeff G's solution and it didn't work at first. It worked only when I kept the data directory as the default (C:\Program Files\PostgreSQL\9.5\data). So then I tested further and tried setting the data directory to somewhere outside of any user profile directories (i.e. somewhere that isn't under C:\Users). For example, C:\postgres-data and this worked.
I then just tried using that directory with my default user, and not bothering with the postgres temp user as outlined in Jeff G's solution and that also worked. So in the end, it had to do with my data directory being somewhere under C:\Users. As long as it was outside of that, it worked.
None of these answers here helped me, finally I solved this problem by creating the folder before the installation (C:\PostgreSQL\data) and giving it full access for the group "Users".
Windows 7 x64, postgresql-9.5.2-1-windows-x64
Hope It's Work.
1.)Uninstall PostgreSQL
2.)Delete the postgres user if it still exists :
net user postgres /delete
3.) Create the postgres user with a password you can remember:
net user /add postgres
4.) Add the postgres user to the Administrators group:
net localgroup administrators postgres /add
5.) Add the postgres user to the Power Users group
net localgroup "power users" postgres /add
6.) Run a command window as the postgres user:
runas /user:postgres cmd.exe
7.) Change user postgres and install postgresql
8.)Back your and remove the postgres user from the Administrators group.
net localgroup administrators postgres /delete
I had the same error ("Failed to load SQL modules into the database cluster.") when installing on W2K12R2 using the EnterpriseDB installer linked to from the PostgreSQL Windows download page. I tried running the installer with admin privs, and using the postgres-user solution offered by Jeff G, but neither worked. Finally I tried the second installer, BigSQL, and that installed without issue.
When installing PostgreSQL, do not use the following symbols in your database's admin password: %, <, and >.
Bug report and problem solution here
Changed the data directory to something other than the installation directory of postgres
Make sure NETWORK SERVICE has read/write permissions on that folder, the installation was failing for me until I did this.
I had this issue too with 9.5 and got around it by:
Installing with the default data folder.
Making sure my new data folder had full control access for the "NETWORK SERVICE" account.
Then changing the default PGDATA folder as per this instruction: https://wiki.postgresql.org/wiki/Change_the_default_PGDATA_directory_on_Windows
I had the same problem, and noticed that some Postgres .bat files were opening in a text editor. Text editors opening files during installation isn't too uncommon, but I noticed these batch files were setting directory permissions. I then found that .bat files were set to open in a text editor (Notepad++) by default. I changed the default program for .bat files, uninstalled Postgres, re-ran the installer, and it worked perfectly. Hope this helps.
I had the same problem before. I solved this by installing Visual Studio C++ Express first.
I had the same experience as #gomisha. #Jeff G's solution did not work for me no matter which user ran the installer.
As long as the target data directory was anywhere under c:\users, the install or database cluster init would fail.
I was successful after creating c:\postgresql-data and ensuring that the postgres user had full access in the 'effective access' tool.
Note: I did not use control userpasswords2 to set up the postgres user; I did it through the traditional crappy Windows 10 user wizard that tries to make the user sign up for hotmail. I did run the install as postgres.
I was getting this issue with the BigSQL windows installer PostgreSQL-9.6.5-1-win64-bigsql.exe
The problem turned out to be that my system path was too long. After removing some uncessary junk from my System Path, and then reinstalling, the problem was gone.
One of the answers here is the only thing that worked on my machine:
I had the same error message when trying to install 9.2.4. My issue
was because even though the Win2k8 server had %SYSTEMROOT%\system32 as
part of the path, no programs could "see" anything in
C:\Windows\system32. The installer heavily uses icacls.exe during the
init routine. Since my path was screwed up, the installer bombed out.
Once I explicitly added C:\Windows\system32 to the SYSTEM's Path
environment variable and re-ran the installer as an admin, everything
worked fine.
Credits to the user.
Go to services.msc
Search for postgres service
Go to Log On tab
Select local account
Profit
The alternative solution for problems with PostgreSQL installer is setting this up with a Docker.
Install Docker Desktop
https://www.docker.com/products/docker-desktop/
Start installed Docker Desktop
In PowerShell, run:
docker pull postgres
In PowerShell, run:
docker run -d -p 5432:5432 --name postgres -e POSTGRES_PASSWORD=mypassword postgres
Now you can connect to the Postgres server for example with pgAdmin on the same machine, using:
host: localhost
port: 5432
maintenance database: postgres
username: postgres
password: mypassword
I think this would be better as individual comments above, but I don't have the required rep. I just spent days on this, with Postgres 10 on Win 10 Creators. My "answer" was to let Postgres put the data in its default install folder instead of my User folder (where it would be automatically backed-up).
1. This problem can happen with no reported install errors at all. On my very first try, I saw:
Failed to load SQL modules into the database cluster.
But that seemed to be due to:
Executing C:\Users\loren\AppData\Local\Temp\postgresql_installer_aee8e5a76f\vcredist_x64.exe /passive /norestart
Script exit code: 3010
MSI (s) (AC:FC) [14:21:35:341]: Product: Microsoft Visual C++ 2013 x86 Minimum Runtime - 12.0.40660.
Restart required. The installation or update for the product required a restart for all changes to take effect.
The restart was deferred to a later time.
Restarting Windows after the failure of the rest of the Postgres installation did not let Postgres run.
Once VC was in place, uninstalling and re-installing Postgres (still with its data in my User folder) completed with no reported errors. But every attempt to access it, by any means, still resulted in something like this:
C:\Program Files\PostgreSQL\10\bin>psql
psql: could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
The RawCap sniffer showed TCP SYN followed immediately by RST,ACK on localhost for both v4 and v6 for each try. Netstat did not see port 5432 in use at all. All Postgres runtime logs were totally empty. In Windows Services, I could manually start the postgresql-x64-10 service, but it immediately stopped itself, with the note that some services do that normally.
2. I tried moving the data directory via the Postgres wiki procedure. Apparently for Postgres 10 it is incomplete. It does not deal with:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\PostgreSQL\Installations\postgresql-x64-10\Data Directory
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\PostgreSQL\Services\postgresql-x64-10\Data Directory
C:\Program Files\PostgreSQL\10\pg_env.bat
C:\Program Files\PostgreSQL\10\scripts\serverctl.vbs
But fixing every data file instance I could find did not let it run. And even after fixing all those, and uninstalling and re-installing again with the default location, the new pgAdmin4 somehow still remembered my original User data directory location!
3. I did not try giving NETWORK SERVICE read/write permissions on my User folder. Once the default install worked I wanted to get on with my original project... Maybe that would have worked.
