I've installed Kali Linux from the windows store, and have been trying to get postgresql to run, but it doesn't work. I've googled it, and lots of people have the same kind of error but none have the same one as me. This is the error message I get:

  • What's the output from sudo netstat -tlapn |grep 5432? Nov 28, 2023 at 20:10

There it says clearly...

"could not bind IPv4 address" "Is another postmaster already running on port 5432

Try with this.

ss -putona | grep 5432


nmap localhost -Pn -p 5432 -sV

And verify that there is nothing running on that port.
