I have 2 computers (Win 10 and Mac) and need to access a RDS Postgres database. Connection is secure via a bastion host and ecs instance. When I configure TablePlus like this:
It works perfectly on the Mac but not on Windows. I checked a bit and recommendation is to create a tunnel via Putty to forward the port 5432 to a local one and then try to access the db with a local IP. But no success.
I would like to know if there is a specific setting in TablePlus or something I'm missing that will allow me to access the database on my Windows computer? I tried also with pgAdmin and same results.

I have created a postgresql database on my local machine and I want to connect to that database on my virtual linux(centos) machine. But I could not figure it out. What should I type in the host section ? (Link here)
You need to port forward the localhost to the virtual machine using something like this you need to enter your host and guest IPs and ports accordingly.
I am trying to access a postgres server that has limited IP access in pg_hba.conf file.
I am trying to use dbeaver to access it.
I am - computer A
postgres server - computer C
server i can access postgres server from - computer B
In my computer I have this view.
As far as I understand I need to trick my computer into using the computer B.
So when i write postgreserver.blaah.com into host/ip and port 5432. It will ssh to computer B and then access it from there.
So in my ssh config file i wrote this:
LocalForward 5432:postgreserver.blaah.com:5432 myuser#server.b.com
Well this didn't work.
Any suggestions?
I don't think you should do anything in your ssh config (and which computer's ssh config was it?). DBeaver's SSH tab is an alternative to manually setting up your own tunnel.
If you have already manually set up your own tunnel, then you would just point DBeaver to it, you wouldn't tell DBeaver that it is using a tunnel. It doesn't need to know.
If you want DBeaver to set up the tunnel, then "computer_B" would go in the Host/IP field of the SSH tab. "computer_C" would go in the Host field of the Main tab.
I ended up using
ssh -L5432:databasehostname:5432 intermediatehostname
So this is running in a random shell somewhere on my screen while i am working with the database.
In DBeaver the hostname is localhost and port is 5432
and i am using Main connection tab not ssh tunnel.
I am running postgresql in WSL Ubuntu on windows. Everything is up to speed, my data is loaded and I wish to access the database through some graphical interface. I was thinking pgadmin4.
Is it possible to accomplish this through a windows install of pgadmin4? I installed pgadmin4 on windows and tried to connect the traditional way in the GUI through localhost but am not getting a connection. I figure there may be a special method here.
For everyone else stumbling across this: The best way to do this (that I know of) is to SSH into your local WSL and then configure the SSH in pgAdmin to that.
I have yet to figure out, how to use this remotely.
As long as postgres is running within your wsl2 instance (check with sudo service postgresql status) then within PgAdmin 4 (running in windows), all you need to do is click to "Register" a new server.
Then, while entering the Connection data, set host to localhost and port to 5432 (unless you specified unique port within your postgres instance when creating in wsl2.
See this answer for more detail
There is no special way needed, you should be able to get a connection. Just like your dev http ports are exposed to your browser on Windows, your db port should too.
I had to manually add localhost to pg admin though which is a bit weird.
Make sure your db service is up and running on Ubuntu, sometimes the db service is killed for no reason.
To see if your PostgresSQL service is up or not:
sudo service postgresql status
If it's not, start the service:
sudo service postgresql start
Ubuntu 16.04 LTS
I have followed the guides which all say the same thing; to enable remote connection to a postgres server, update the postgresql.conf file, update the pg_hba.conf file and make sure the port (5432) is open and firewall is not blocking.
When I attempt to connect to my server from the remote machine using the following command, I receive no response (for example, 'Connection refused...'). It hangs as if the firewall has DROP policy, but I checked and the host's firewall is ACCEPT all. Here is the command:
psql -h 45.67.82.123 -U postgres -p 5432 -d mydatabase
I have googled extensively and can't find anyone else who's psql request sits with no response from the host server.
Edit: I should mention I have been connecting locally on the host machine. I should also mention that the data directory on the host machine is in a non-default location. I have my cluster on a mounted drive, in case this could affect the remote connection.
Solution:
It is my first AWS instance and I didn't know they have their own firewall rules on the platform. So I was highly confused by the fact all my policies were ACCEPT on my server. Turns out you are behind AWS firewall and you have to go onto the platform to add/change security groups etc. In the past when I've used Digital Ocean droplets or Linodes, the firewall policy on the vps is all I need to change. AWS threw me another curveball there.
I am running openerp(odoo) application from amazon cloud server using putty and it is ubuntu Headless(NO GUI) server. PostgreSQL is the database used for this application. Right now I am only able to access it in command mode as there is no gui in Putty. In Windows, I have installed pgadmin3. Is it possible to access it from here by configuring?
You can configure your security group to open up the postgres port accessible from your IP address (I would highly recommend the access to be limited that way). After that you can just point your GUI client the external IP address of your instance using the port where the service is running on.
I suggest you to use pgadmin gui tool to access postgres database.
You can set up an SSH tunnel in putty and use that to access the remote database with your local pgadmin3. This is a very good and secure way to do things.
First, in Putty (Connection / SSH / Tunnels) add a source port of your choice, 5000 for example. Then enter localhost:5432 for Destination (providing postgres is running on port 5432 on the server). Press Add and save your session. Next time you open your ssh connection with Putty, the tunnel will be active.
After this, set up a new connection in pgadmin3, Host: localhost and Port: 5000 (and your username and pasword, of course). Now, if the putty session is active, you should be able to connect.
In postgresql.conf file, find a line called
listen_addresses = 'localhost' and change it to '*'
Next in pg_hba.conf add this line in IPV4 local connections,
host all all (Your external ip address in CIDR format) trust
Finally restart the database using this command,sudo service postgresql restart
