Create dump file using pg_dump tool - database

I'm trying to create a dump file using the pg_dump tool as specified here, but I keep getting this result:
$ PGPASSWORD=mypassword pg_dump -Fc --no-acl --no-owner -h localhost -U myuser app_db > app_db.dump
Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" and accepting

I'm using OSX Lion for a rally sort time, and still don't know how can I open or close ports, so, If that's the issue, please tell me how can I open it, if the problem is other thing, please tell me what it is (and how to solve it)
Thanks

You need to have postgresql installed and running

Unable to remotely connect to postgres server on vps

I set up a postgres 14 db on my windows server 2016 vps. I configured the port to be 5432 and set listen_addresses = '*' inside postgresql.conf and added host all all 0.0.0.0/0 md5 and host all all ::0/0 md5 to pg_hba.conf. I checked that the service was indeed running when opening the windows Services application and I restarted the service after every change. I also added a new inbound rule on the firewall to allow port 5432. And I've tried restarting my entire vps.
Whenever I try to connect to the postgres server remotely (psql -h <my vps ip address>), I get met with Connection timed out (0x0000274C/10060) Is the server running on that host and accepting TCP/IP connections?. Am I somewhere missing a step?

Getting: Could not connect to Server - Connectin refused with postgres

I have Postgres 13 and pgAdmin installed on my Windows machine. It worked for like ~six month, until I hat do restart my machine. After restarting the computer (which I had not done because there was an update), I am trying to connect to Postgres via pgAdmin as always and I get this
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?
Some answeres on stackoverflow suggest, to edit the postgresql.conf file which I a) do not find in my postgres installation and b) I think is not the correct solution for me because it worked without any problem until I restarted my machine.
Why is that? It feels like postgres is not starting? Although this is a wild guess...

PgAdmin- Postgres: could not connect to server: Connection refused (0x0000274D/10061)

Hi i want to use PostgreSQL for a school project and whenever i open the server in Pg Admin i got the same issue
when i first open Pg Admin i enter the password that i entered in the installation and when i click to server(1) it requires password for user "postgres" i use the same password but it tells me:
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 1500? 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 1500?
i don't know what does it really mean .. cause i'm new to databases and servers
i reinstall all postgres & Pg admin : same issue
i restart the server in services-postgres.. : same issue

please help !!
and thank you !
On windows:
click on windows
search for services
scroll down to postgresql
right-click on it and select properties
click on the startup type dropdown button and select automatic
then click start
this will automatically run your postgresql
I am facing the same problem and as I edited the port to 5432 it worked. In my case, Postgres was running on 5433 and I changed it to 5432
Pretty sure the problem is due to this:
... accepting TCP/IP connections on port 1500
Postgres runs by default on port 5432. Try changing the port setting to 5432.
For me the issue is due to not starting a server, so you should start the server, one way to do it is to cd to postgresql bin and start it with pg_ctl, here is an example:
cd "C:\Program Files\PostgreSQL\14\bin"
pg_ctl -D "C:\Program Files\PostgreSQL\14\data" start

Unable to connect to postgres server remotely(ubuntu 16.04)

I am pretty new to postgreSQL. I am running version 9.5 of it on my main machine. I am trying to establish a telnet connection from my virtual machine. Before doing that I have configured the postgresql.conf and pg_hba.conf files to accept connection from remote machine in the same network.
However when I start the postgresql service using:
service postgresql start
The process show the status:
active(exited)
and the telnet connection is also refused(when i run telnet x.x.x.x 5432). Also when i start the postgresql service using
systemctl start postgresql#9.5-main
the status is active(running) but the telnet connection is still refused. Can anyone tell me how to establish the telnet connection? I dont really know whats going on and I am new here so please dont mind if its a noob question

Connection refused to PostgreSQL server

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.
