Remove old project dbs from macbook

Question

During my time in school and creating my own applications, I've had to delete projects from my laptop to free up space. Is there a way to remove the db from said deleted projects if the project is no longer on my computer? I've had an issue before , when I was starting out that I had to delete my project and start over. But I had forgotten to drop the db. So when I went to create the project again with the same name, it told me the db already exists.

So is there a way to remove stale dbs that do not correspond to a project anymore?

EDIT Sorry, I may need to clarfy. I am trying to clear up space on my laptop by remove old dbs that I forgot to drop before deleting the project folder. I no longer remember the names of the deleted projects

If you use postgres just log in as your Postgres user and run \l You are going to see all the DBs you have, and then could drop them with: dropdb 'database name'.

If it says DB already exists then run

rake db:drop

It will drop the existing DB
