I get this error message (see below) and do not know what to do about it.
Error message:
"psql: error: connection to server at "localhost" (::1), port 5432 failed: Connection refused (0x0000274D/10061) Is the server running on that host and accepting TCP/IP connections?
connection to server at "localhost" (127.0.0.1), port 5432 failed: Connection refused (0x0000274D/10061) Is the server running on that host and accepting TCP/IP connections? "
I am using Windows 10 (64bit) and have tried the same thing on Kali and Ubuntu and still was not able to use postgresql.
Does anyone have a suggestion what do to? However, please use "language" that I can understand or at least look up simply because I am new to programming (in general). Thank you
P. S. I tried various different things such as using pgAdmin to change ports but cannot solve a problem. I do not know if this is important but I istalled postgresql via Binaries because regular Installer was giving an error message telling me that comspec does not point to cmd.exe even though it actually did...
If you
properly set up your db (installation and initialization using initdb), and if you
have your data directory containing your postgresql.conf and pg_hba.conf among other things, and you
properly started the postgresql service,
then I can assume your problem is in the connection string.
Try to include the superusername and/or db name, your error maybe due to psql connecting to user localhost which does not exist inside your db.
Try to run psql with -U and -d options:
psql -U postgres -d postgres

While installing PostgreSQL on Windows 11 I get the error:
the database cluster initialization failed
then SQL Shell gives me an error

Is the server running on host "localhost" (127.0.0.1) and accepting

There's even no Postgres in Services and the data folder is empty. So I uninstalled it and got this error while doing so:
error stopping service PostgreSQL-x64-13
After this, I've tried many different ways of reinstalling Postgres, including running it as Admin, creating a separate user named postgres with Admin rights, etc. In fact, this comprehensive article offers a lot of different ways to deal with this issue: https://forums.holdemmanager.com/general-support/150771-solved-postgresql-database-cluster-initialisation-failed.html
However, none of them worked for me. It seems that I exhausted all possible solutions. Any ideas on what I can try now?
I am using pgAdmin4 and developing a node.js app.I had an abrupt shutdown of the computer and I can no longer connect to the postgresql server.
The error I get when trying to connect is :
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?

I tried to run postgres -D /usr/local/var/postgres/ as suggested in this SO answer. However it gave me the following error :
postgres: could not access directory "usr/loval/var/postgres": No such file or directory
Run initdb or pg_basebackup to initialize a PostgreSQL data directory.
So I just manually deleted the postmaster.pid file inside the PostgreSQL/.../data folder. But I still cannot connect to the database server.
I have checked the postgresql.conf file, and
the listen addresses is already set as listen_addresses = '*', and the port is set to 5432.
I also tried deleting the pgAdmin file in the AppData/Roaming folder.But it gave me an error:
The application server could not be contacted
and then afterwards the same problem of not being able to connect to the server happens.
Funny enough, it was a matter of just deleting the pdAdmin file in AppData/Roaming folder, and then restarting the computer and restarting the pgAdmin4. That solved it for me.
Meet the same challenge while settings up PostgreSQL to work with a Python/Django project.And i resolved the issue here, after reading the official PostgreSQL-9.6.16 documentation.
I successfully installed postgres through homebrew, and i set it run automatically by doing
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
So, right now i can access to psql from my terminal (i use iterm2 + oh my zsh)
psql (9.6.1)
Type "help" for help.

The problem is, postgres management tools like postico, pgadmin cannot access to it
for postico, error message is
could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5435?
could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5435?
which is weird because from my understanding, accessing to the database from terminal and management tools are basically the same if configured correctly
My pg_hba.conf and postgresql.conf are set as default (didn't make any changes there), but i tried doing
listen_addresses = 'localhost'
=>
listen_addresses = '*'
(restart server)
still didn't work
Please help!
Port 5435 is not standard for PostgreSQL. Are you sure PG is running on it? If you didn't change it in postgresql.conf it must be 5432. Please check it.
must check pg_hba.conf. If there doesn't have much restriction, you can put to end of this file by below line:
host all all all trust
After that, reload/restart instance.
Check if your PC is using firewall. If yes, please turn off it.
Postgres.app documentation says this, verbatim: Once your path is correctly set up, you should be able to run psql without a host. (If not, check that the correct version is being loaded in the PATH by doing which psql) This is not so for me.
Here's where I'm at. WITHOUT the Postgres.app on (No elephant anywhere):
$ which psql
/Applications/Postgres.app/Contents/Versions/9.3/bin/psql
This is correct, and what Heroku says to look for. Heroku also tells me the command below should work, but it doesn't:
$ psql -h localhost
psql: could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (fe80::1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
however I can get it to work when I double click postgres.app and turn it on.
$ psql
psql (9.3.3)
Type "help" for help.

The docs specifically say that it should work WITHOUT the localhost. Am I set up correctly or do I need to change something? The code right above makes me feel like everything is working properly, but the "should work without a host" thing makes me unsure.
You're using the psql from postgres.app. It's configured to, by default, connect to the database server from postgres.app. That won't work if postgres.app is not running.
With our without -h, you must have postgres.app running.
If you want to run a background PostgreSQL server, postgres.app isn't what you want. Install from Homebrew or use the EnterpriseDB installer packages.
I just installed PostgreSQL on Snow Leopard and can't connect to the database server via pgAdmin 3.
I'm on my local machine, however I keep getting this error:
Could not connect to server: connection refused. Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5423?
I'm a bit of a noob when it comes to Postgres, so I'm not really sure what the problem is.
I can, however, log in through the command line, via psql -U postgres, and start and stop the server successfully.
Any help would be much appreciated.
The error message pointed out that you tried to connect to server on port 5423. However, postgres server listens on 5432 by default.
From your above comment (SHOW port; gives me "5432"), I think you need to change the port to 5432!
UPDATE: Tuan Dang spotted it. I'll leave this answer in place in case it helps someone else for whom the issue isn't quite the same.
Since you can connect via the command line, run:
SHOW port;
from psql. You'll probably see that the port is not 5432. You need to connect to the port PostgreSQL is actually running on from your application.
It's also possible that it just isn't listening on TCP/IP. Run:
SHOW listen_addresses;
to see what it's listening for.
The reason you can connect via the command line is likely to be because the command line psql you're using is connecting over a unix socket (since you didn't specify a host) and your app is connecting via tcp/ip.
