PostgreSQL location with Postgres.app I am using the postgres.app. I get a terminal window when I start the postgres app. However, when I go into a bash shell and type in psql it says Command not found. I assume the path to the app is not set in my profile. How can I find out where the postgres.app is located and how do I tell that my profile?
You just need to set your $PATH up.

This is covered on the Postgres.app website.

Add this to your ~/.bash_profile:

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


... then reopen your shell/terminal.
