I have installed PostgreSQL. However everytime I try to connect through PGAdmin or through psql it gives me the below error.
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 checked the postgresql.conf file and the line: listen_addresses = '*' isn't commented out.
Also this is how my pg_hba.conf file is set:
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
Can anyone please advise on how I can resolve this issue?
Thanks!
Use services "start -> run -> services.msc" and look for the postgresql-[vers] service.
If it is not running try to start it, if it won't start open the event-viewer (start -> run -> eventvwr) and look for error messages relating to the PostgreSQL service.
In my case it was postgres.config. The port was somehow changed to 5433 in there and I do not remember doing it myself lol. So make sure your ports are matching up in your project vs postgres.config
pg_hba.conf.txt has to be called pg_hba.conf.
Beyond this, when you have en authentication error you will get a message similar to:
psql -U nonexistent
psql: FATAL: Peer authentication failed for user "nonexistent"
The error you are getting means most likely that PostgreSQL is not started on this server.
You can start PostgreSQL with:
service postgresql start
service postgresql status
This worked for me -
In C:\Program Files\PostgreSQL\data\postgresql.conf set listen_addresses ='localhost'
Then try -
pg_ctl -D "C:\Program Files\PostgreSQL\9.5\data" start
if already try restarting using pg_ctl
It works for me.
Remember, whatever comes after -D should be the path to where you installed PostgreSQL, to the data folder, which holds the pg_hba.conf and postgresql.conf files.
pg_ctl start -D "C:/Program Files/PostgreSQL/9.6/data"
Maybe you can try this.
Open cmd and insert.
"C:\Program Files\PostgreSQL\11\bin\pg_ctl.exe" runservice -N "postgresql-x64-11" -D "C:\Program Files\PostgreSQL\11\data" -w
Hit enter...

I`m using postgresql database on my web server (ubuntu + nginx) and it works with backend app. I want to connect remotely using pgAdmin
but it always throw this error:
could not connect to server: Connection timed out(0x0000274C/10060)
Is the server running on host "ip" and accepting
TCP/IP connections on port 5432?
I already add to my pg_hba.conf this line:
host all all all password
and also add to postgresql.conf line:
listen_addresses = '*'
netstat -nlt does next result, and it`s enough in tutuorials i found, but still cant access my database
Found a solution, it works as well after this command:
sudo ufw allow 5432/tcp
Open file named pg_hba.conf
sudo vi pg_hba.conf
and add this line to that file
host all all 0.0.0.0/0 md5
It allows access to all databases for all users with an encrypted password
restart your server
sudo /etc/init.d/postgresql restart
I am on Windows 10 using WAMP, I added PostgreSQL and PhpPgAdmin, everything was working fine. Today I can not log in to PostgreSQL through PhpPgAdmin or a php_pdo web app.
I tried editing pg_hba.conf in 2 locations c:\PostgreSQL\pg96\init\ and c:\PostgreSQL\data\pg96\ and changed the 'method' to trust as per many answers here, none of the CLI answers worked either.
I also restarted "WAMP" and even the whole computer, but no luck.
The default password worked before postgres and root but not now.
How do I reset the postgre password?
UPDATE
runing psql -U postgres returns;
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

contents of pg_hba.conf
# TYPE DATABASE USER CIDR-ADDRESS METHOD
# IPv4 local & remote connections:
host all all 127.0.0.1/32 trust
host all all 0.0.0.0/0 trust
# IPv6 local connections:
host all all ::1/128 trust
so after a lot more diging, it was not that the password was wrong, but for whatever reason PostgreSQL was not even running. Windows is such a PITA!
in the end, running pg_ctl -D "C:\PostgreSQL\data\pg96" start from CMD got it going. Now we will see if it starts tomorrow.... I miss my Unix Environment.
----- UPDATE -----
While the above code works, it is moving in the wrong direction.
goto Control Panel->Administrative Tools->Services and find 'PostgreSQL ...' in the list. Right click and open Properties.
My Startup type: was set to 'Automatic' but it was not starting, I set it to 'Automatic (Delayed Start)' and now it is working, automagically!
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:
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" (127.0.0.1) and accepting TCP/IP
connections on port 5432?
command
service --status-all
tells that postgres works
[ + ] postgresq works
Next I changed next files
sudo nano /etc/postgresql/9.5/main/postgresql.conf
#listen_addresses = 'localhost'
to
listen_addresses = 'localhost, server_ip, *'
sudo nano /etc/postgresql/9.5/main/pg_hba.conf
add
host all all server_ip/24 trust
then command
psql -U postgres -h server_ip
and error
psql: could not connect to server: Connection refused
Is the server running on host "95.213.200.26" and accepting
TCP/IP connections on port 5432?
The following chain of actions leads to a slightly different error
command
which psql
answer
/usr/bin/psql
sudo su - postgres
No directory, logging in with HOME=/
psql
psql: could not connect to server: Permission denied
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
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 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.
Please read before replying it as duplicate (as it perhaps can happen). I am running my postmaster (postgres) server. See below for 'sudo netstat -anp|grep 5432' output?
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 29606/postmaster
unix 2 [ ACC ] STREAM LISTENING 1650581 29606/postmaster /var/run/postgresql/.s.PGSQL.5432
unix 2 [ ACC ] STREAM LISTENING 1650582 29606/postmaster /tmp/.s.PGSQL.5432
I am able to connect from localhost using
psql -h localhost (OR 127.0.0.1) -d <DB> -U user -W
But when I try to connect from other hosts using tcp, by specifying
psql -h ip_add_postmaster -d <DB> -U user -W
It throws:
psql: could not connect to server: Connection refused
Is the server running on host XXXXXX and accepting TCP/IP connections on port 5432?
What's wrong here?
pg_hba.conf
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all peer
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
In postgresql.conf,
listen_addresses = 'localhost, 127.0.0.1, ip_add_postmaster'
Note: ip_add_postmaster is same as my Elastic IP and not public DNS. If this information
matters.
What am I doing wrong here? Machine is hosted on Amazon EC2 and have open the port 5432.
As your netstat output indicates, it's listening at 127.0.0.1:5432 which is localhost. That is only connectable from localhost ;)
Set listen_addresses='*' in your config and it will work.
[edit]
Other things to check:
is the amazon firewall blocking anything?
is iptables blocking anything?
But first make sure the listening address is correct, your netstat output shows that it won't work like this.
listen_addresses='localhost, private_ip' fixed the issue. I was not able to start postmaster server on elastic IPs. Once postgres server started o localhost and private IPs, I was able to connect.
One other issue I have found was if you end up with two Postgres installations, the second one can choose non-default port (in my case it was 5433 i/o 5432). So checking the port in postgresql.conf might be a good idea.
I ran into this issue and tried all sorts of fixes I found across SO, and want to add a simple solution that worked for me after realizing it had to do with permissions in my case.
Simply, if you're running a psql server on Windows, you are initially restricted to the default postgres superuser for logging in, launching the server, and so on.
So, first try running from the command line:
psql -U postgres -h localhost -p 5432
and enter your password at the prompt. If you've managed to login and the server is up, then it was a permissions issues. From here, you can create a role for yourself that has login privileges to whatever database you are trying to run.
If the error persists, then consider checking postgresql.conf as mentioned above, to make sure default IP is set to * or localhost, and the port set to 5432 or whatever port you want as default.
I also ran into the same issue. On debugging, it was nothing related to the port, but due to some missing directories in the Postgres folder.
While updating Mac OS (from 10.13.1 -> 10.13.13), some folders in the directory /usr/local/var/postgres/ gets deleted. The fix was the adding the missing directories:
mkdir /usr/local/var/postgres/pg_tblspc
mkdir /usr/local/var/postgres/pg_twophase
mkdir /usr/local/var/postgres/pg_stat
mkdir /usr/local/var/postgres/pg_stat_tmp
mkdir /usr/local/var/postgres/pg_replslot
mkdir /usr/local/var/postgres/pg_snapshots
mkdir /usr/local/var/postgres/pg_logical/{snapshots,mappings}
