2. In the Terminal, type `psql` and press Enter.
3. If PostgreSQL is installed, you will see a prompt asking for your username. If not, you will receive an error message indicating that the command is not recognized.
You can also check the PostgreSQL folder in the Applications directory. Navigate to `/Applications/PostgreSQL.app/` to see if the directory exists.
Checking PostgreSQL Installation on Linux
To check if PostgreSQL is installed on Linux, follow these steps:
