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.
