I am trying to connect to a postgreqs cluster with the pgAdmin, but even with the connection data being correct, pgAdmin returns the following error:
The cluster exists and are online, port and hostname are correct, but I'm still getting this error, how can I solve this?
Update
Postgres version:15.0
Psql version:15.0
I can connect to server using psql

I've been learning postgresql recently and made a lot of mistakes with the project I started with so I decided to drop the whole database which was called postgres.
And I kept receiving this message:
[55006] error: cannot drop the currently open database
so I closed it by force using:
DROP DATABASE postgres WITH (force)
and now I can't create new data sources or log in to my postgres account and I keep receiving this error:
error: connection to server at "localhost" (::1), port 5432 failed: FATAL: database "postgres" does not exist
what can I do about it?
I couldn't find a solution I could try because I haven't found a similar problem yet please direct me to a solution
I am trying to connect a database on Kubernetes (remote server) and I set all the necessary connection parameters on DBeaver. However, while I can connect the same database using pgAdmin, I cannot connect using DBeaver and it gives the following error:
error
I checked many pages on the web and could not find a solution for that. I am not sure if it may be related to Driver, but I can connect to another PostgreSQL databases on my local Docker container.
Any idea to fix the problem?
I'm trying to connect to my localhost Postgresql database and I'm getting an error:
Connection to database... failed
No other message provided.
I'm using using pgAdmin3 connecting to Postgresql 10.1
I've been connecting to this database using the same user (and password) and another user via my app successfully all the while but it just failed to connect to the database now. No users seems to be able to connect to the database
Edit: after further checks I noticed Postgresql is not listening on the port 5432.
I've checked the postgresql.conf file and it looks fine
listen_addresses = '*', port = 5432
I'm kind of new to Postgresql. Sorry if it's something obvious I'm missing out. Still looking for how to start postgresql or make it listen on the port.
I am currently setting up a postreSQL server on my Windows computer.
I want to create my first database, but couldn't create the createdb function due to a password authetification failed. Thus I found the following question on this website:
How to configure postgresql for the first time?
However, I think I forgot the ; at the end of :
ALTER USER postgres with encrypted password 'xxxxxxx';
And now, when I try to launch psql, I have the following errors:
Server [localhost]:
Database [postgres]:
Port [5432]:
Username [postgres]:
Active code page: 1252
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?
Press any key to continue . . .
Any idea of what I could do to solve the problem?
Do you think it is really the missing semi column that caused the problem?
Do you have any tutorial on how to setup a postgreSQL database on Windows? All the one I found until now were for Linux only.
The error you're getting appears to be from Postgres not currently running, rather than an authentication error as you're presumed. The PSQL client or whatever PG client you're using is attempting to establish a connection on the default port but nothing is there.
If Postgres isn't currently running, try finding it (Via CTRL-Alt-Delete). If it's running, try terminating it and starting it up again. Hopefully that fixes the problem... Otherwise your port 5432 might be blocked for some reason.
If all fails, I am still skeptical the parentheses could cause this error because it's not an authentication error. Try to reinstall Postgres with a clean install.
I am on Linux, trying to connect to SQL server.
Using sqlplus, as below:
sqlplus username/password#server:port;
Getting ORA-12537 error - "TNS: Connection closed". This error comes after a long wait.
While trying to figure out what the issue was, I got -
"TNSPING server:port" returned error : TNS-12537 TNS Connection closed.
"TELNET server port" is working fine. It shows connected status.
Also tried using Easy connect after reading another post LINK. This is the command I tried "sqlplus username/password#//server/port". It gave me error ORA-12541 : TNS: No listener.
Just want to add that I am able to connect to an Oracle db using sqlplus, with no problem.
Version is 10.2.0.4.
Any idea how to fix this? Appreciate the help!
UPDATE: I did not know sqlplus can't connect to SQL server. I tried connecting using mysql, but got an error:
MYSQL -h server -P port -u username -ppassword
returned error : ERROR 2013 (HY000): Lost connection to mysql server at 'reading initial communication packet', system error 104. This error also comes after a long wait.
Thanks for your help!
You will need an SQL Server specific client to connect to SQL Server, sqlplus is a oracle client and mysql is a command line client for the mysql server. Microsoft provides a JDBC driver at http://msdn2.microsoft.com/en-us/data/aa937724.aspx or a Linux ODBC driver at http://www.microsoft.com/download/en/details.aspx?id=28160. This might help if you have some kind of software that can use those drivers, e.g. RazorSQL (http://razorsql.com/features/sqlserver_features.html)
