Postgresql service not starting on Kali Linux

Question

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:

'''Starting PostgreSQL 12 database server: mainError: /usr/lib/postgresql/12/bin/pg_ctl /usr/lib/postgresql/12/bin/pg_ctl start -D /var/lib/postgresql/12/main -l /var/log/postgresql/postgresql-12-main.log -s -o -c config_file="/etc/postgresql/12/main/postgresql.conf" exited with status 1: 2020-05-13 11:24:14.677 DST [4603] LOG: starting PostgreSQL 12.2 (Debian 12.2-4) on x86_64-pc-linux-gnu, compiled by gcc (Debian 9.3.0-8) 9.3.0, 64-bit 2020-05-13 11:24:14.678 DST [4603] LOG: could not bind IPv4 address "127.0.0.1": Address already in use 2020-05-13 11:24:14.678 DST [4603] HINT: Is another postmaster already running on port 5432?

Answer 1

There it says clearly...

"could not bind IPv4 address" 127.0.0.1 "Is another postmaster already running on port 5432

Try with this.

ss -putona | grep 5432

Or:

nmap localhost -Pn -p 5432 -sV

And verify that there is nothing running on that port.
