For clarification, please note that I have found several similar questions on stackoverflow, but I could not fix my issue.
psql: could not connect to server: Connection refused” Error when connecting to remote database
psql: How to Allow Remote Access to PostgreSQL database
I am trying to connect to a postgres DB installed in a remote server.
To create a connection from the client I am using QGIS plugin (Add PostGIS Layer):
The error that occurs is:
could not connect to server: Connection refused (0x0000274D/10061) is the server running on host "localhost" (::1) and accepting TCP/IP connection on port 5432
Additionally I added the host's IP Adress in the Host field, but then another error message occurs:
could not connect to server: Connection timed out (0x0000274C/10060) Is the server running on host "hosts_ip_adress" and accepting TCP/IP connections on port 5432?
My settings are:
Postgres installed version is 10.0 with PostGIS extension
Host operating System: Windows 7
Client operating System: Windows 7
I edited pg_hba.conf to:
host all all 0.0.0.0/0 md5
and changes listen parameter in 'postgresql.conf' to:
listen_addresses = '*'
both files are located in C:\Program Files\PostgreSQL\10\data
restartet pgAdmin4
My devices are in the same network. Each one is connected via LAN cable.
I suppose that a firewall is preventing the connection?

I have installed PostgreSQL 13 on Windows 10 using the EDB installer and it seems to work fine. I can connect easily with psql in the included SQL Shell application. However, I can not connect from powershell:
~> psql -U postgres -h localhost
psql: 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?
Any permutation of psql command line switches yields the same result. I checked pg_hba.conf and it looks sane - all local connections are allowed. All the search results for the error code above on the internet assume the server is not running but it is running just fine (see SQL Shell above). Within that shell, all the postgres tables are visible, etc. What do I need to do to connect psql to the server on localhost from powershell?
Default installed pg_hba.conf:
# "local" is for Unix domain socket connections only
local all all scram-sha-256
# IPv4 local connections:
host all all 127.0.0.1/32 scram-sha-256
# IPv6 local connections:
host all all ::1/128 scram-sha-256
The IPv4 line above should cover me in powershell? Yes? tcp connections are allowed in postgresql.conf:
listen_addresses = '*' # what IP address(es) to listen on;
Long time linux PostgreSQL user, first time in powershell on Windows, though...
This morning I found the problem - the EDB installer had setup the postgres service to run on port 5433. After a couple of decades or running it on 5432 I didn't even notice that the number was different in postgresql.conf. It was late...
Something else must be running on 5432. Will check later on.
I run on Windows 10
docker run -it --rm -e POSTGRES_PASSWORD=postgres -p5401:5432 postgres:12.3-alpine
it works fine. I can connect to PostgreSQL, create database etc, all is ok.
But when I run the same docker on my 2nd machine Windows 7 I receive
Could not connect to server: Connection refused (0x0000274D/10061) Is
the server running on host "localhost" (::1) and accepting TCP/IP
connections on port 5401?
What may be the reason? what to check?
That is pg_hba.conf
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
local replication all trust
host replication all 127.0.0.1/32 trust
host replication all ::1/128 trust
host all all all md5
I would say the possible issues are:
1) The server has not actually been started in the Docker server.
Verify server is running.
2) Port 5401 is not visible to the client that is trying to connect.
Ping the port. Could be a firewall issue.
When I install Postgres I make a mistake - change default port from 5432 to 5434 and after all, I change the port back through postgresql.conf. All app connections work fine with new 5432 port value, but cmd interface unavailable:
psql

I try to reinstall Postgres from scratch but without a result. How to change the port for windows cmd?
Clear the PGPORT environment variable, which must be set to 5434.
Then psql will use the default port 5432.
I am setting up project on my windows PC and I have a problem with postgres.
Project is set on docker.
when I run docker-compose up I receive error

I don't know what to do. I have already installed microsoft easy-fix for TCP-IP, shut down windows firewall, changed all connection in pg_hba.conf to trust. Nothing helps. I don't have any antivirus software installed.

edit:
I run psql -h localhost and received
psql: CATASTROPHIC: role "Kamil" does not exist
Kamil is my PC name.
edit2:
is it possible that docker doesn't have access to postgres on localhost?
problem solved
I had to set environment var to DB_HOST=docker.for.win.localhost

If you have this problem, Well, that's because Postgres isn't running locally. I'm not even sure it's installed. The easiest way to do that on a Mac is to grab Postgres.app from http://postgresapp.com and copy it to the /Applications folder.
Trying again:
$ mix ecto.create
