How to put psql on the path when using Postgres.app on OS X?

I just had postgres installed and was not able to run the psql command until I ran the following command in my terminal:

export PATH="/Applications/Postgres.app/Contents/Versions/9.5/bin:$PATH"

Now the terminal knows where to find postgres when I use the psql command.

Remember to replace the version number ‘9.5’ with your current version.
