Download the edb software following link https://www.enterprisedb.com/downloads/postgres-postgresql-downloads

• To specify that the installer should run in text mode, include the –mode text command line option when invoking the installer. Text-mode installations are useful if you need to install on a remote server using ssh tunneling (and have access to a minimal amount of bandwidth), or if you do not have access to a graphical interface.
• In text mode, the installer uses a series of command line questions to establish the configuration parameters. Text-mode installations are valid only on Linux or Mac systems.
• You must assume superuser privileges before performing a text-mode installation. At any point during the installation process, you can press Ctrl-C to abort the installation.
• To perform a text-mode installation on a Linux system, navigate to the directory that contains the installation binary file and enter:

# ./postgres-version-platform.run --mode text
