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 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?

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
I missed a bit with chmod and permissions.
And now got a lot of problems with access to folders.
If I start server I see in browser:

running on host "localhost" (127.0.0.1) and accepting TCP/IP

command
service --status-all
tells that postgres works
[ + ] postgresq works
Next I changed next files
sudo nano /etc/postgresql/9.5/main/postgresql.conf

to

sudo nano /etc/postgresql/9.5/main/pg_hba.conf
add

then command
psql -U postgres -h server_ip
and error
psql: could not connect to server: Connection refused

Is the server running locally and accepting

Wich file permissions do I have to change here?
Check that unix_socket_directories on the server is set to the same directory (/var/run/postgresql) as the default socket directory that was configured when the client was compiled (this requires a server restart).
Alternatively, you can use the --host option of psql or set the PGHOST environment variable to tell the client to look for the socket file in /tmp, where the server creates it.
It looks like client and server are from different installations, otherwise the configured default should be the same for both. Or you have a bad PGHOST environment variable set by accident.
Check listen addres syntax. Use:
listen_addresses = '*'
For the server to listen on both localhost and the server ip.
This question is really hard. I made a great mistake with permissions 777 for / folder and whole system broke. So it is really easier delete server and start new project.
I have just installed the pgAdmin-4, and trying to connect to the default server installed with it (PostgreSQL 9.5). It asks for the password (Which I assume by default it's "postgres"), however, I keep receiving the following message:
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?
I am working on Windows 7.
Any ideas on how to fix this problem?
The first thing is to remove pgadmin from the problem. Try to connect with the command line using psql - if you get the same message you know that the problem is not with pgadmin. If the problem continues with psql then probably your configuration of postgresql is not complete. The issue might be in the file pg_hba.conf - this file controls who is allowed to connect to the backend. You might also check that the server application is running, using an appropriate Windows utility.
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.
ty2kim=#
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.
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.
