Removing postgres connection installed with EnterpriseDB on MacOS

Question

I had earlier installed Postgres using Enterprise DB which is installed by default at location: /Library/PostgreSQL/10

However, because of some database issues I had to uninstall it. I followed all the steps given here.

Today i tried to reinstall the postgres using homebrew. Installation was successful but when I run the below command to start the service it give the following message.

MacBook-Pro ~ % pg_ctl -D /usr/local/var/postgres start

I guess it is suggesting that the port 5432 is in use by another instance of postgres so i am trying to find and stop the process but it does not list any PID:

MacBook-Pro ~ % lsof -i :5432
MacBook-Pro ~ % 

Not sure what I should do next to completely stop the postgres installed via Enterprise DB and start the one installed with homebrew. Kindly guide me with this.
