To run more then one instance of Postgres on one machine each needs its
own port. Have you done that?

The screenshot indicates a different problem, namely pgAdmin(?) cannot
find a running server on port 5434 on the localhost. There can be
several reasons for this:

1) The server is not running, eg the start up script failed.
    Solution: Verify the server has actually started

2) The server is not running on localhost.
    Solution: Verify where it is hosted.

3) It is running on localhost but not on port 5434.
    Solution: Verify that the port variable in postgresql.conf for that
instance is set to 5434 and that the server was restarted to see the change.

3) It is running and is using port 5434, but a firewall rule is blocking
access.
    Solution: Check whether you have a firewall running and whether it is
blocking port 5434.

Hi ,

I am a PostgreSQL user who wants to create multiple instances of PostgreSQL database server. I am using PostgreSQL 9.4 and above.

I tried to create more than 2 instances on Linux environment in which I was successful. But, for windows environment, I tried with the help of pgAdmin4 and with the help of commands (initdb and some more commands.) In both cases , there is some issue related to the ports. Please find the attached screenshot for the reference. 

 

Please help me to resolve the issue.

Hi, I am not sure of your requirements but you can alternatively run a single database cluster with multiple databases. So run the cluster on a single port as in the vanilla windows installation, and then use "CREATE DATABASE dbname;"  for each database you need.

Ignore this if it is not what you are asking :)

I figured the firewall might be an issue. Or it might not.

But guessing won't tell.
