Fw: How do I get rid of version 10 Postgresql completely ?

Hello,

Here's some more information to show the system still containing the uninstalled version 10:

root(at)DESKTOP-1KGGO27:~# sudo service postgresql start * Error: /usr/lib/postgresql/10/bin/pg_ctl /usr/lib/postgresql/10/bin/pg_ctl start -D /var/lib/postgresql/10/main -l /var/log/postgresql/postgresql-10-main.log -s -o -c config_file="/etc/postgresql/10/main/postgresql.conf" exited with status 1:

Hello,

Whenever I start pgAdmin4 I will get this invalid literal for int() with base 10: 'None'.

And the other time I get this see version 10 still exist while playing with Ubuntu WSL.

I had uninstalled version 10 so I am not sure why there is still
remnant lying around in my Windows 10 system.

Can someone kindly advise me how to get rid of PostgreSQL 10 completely.

Thanks in advance,
Karen
