sudo psql command not found

The error "sudo psql command not found" usually occurs when the PostgreSQL client tools are not installed or not added to the system PATH. To resolve this issue, you can try installing the PostgreSQL client tools using your operating system's package manager. For example, on Ubuntu, you can run the following command to install the client tools:

sudo apt-get install postgresql-client

Once the installation is complete, you should be able to run the "psql" command with sudo privileges. If you still encounter the same error, you may need to add the PostgreSQL client tools directory to your system PATH.
