You can try this https://github.com/RAKWireless/rak_common_for_gateway.
Before that, you need to execute the following command first.
sudo apt-get --purge remove postgresql\*
sudo rm -r /etc/postgresql/
sudo rm -r /etc/postgresql-common/
sudo rm -r /var/lib/postgresql/
sudo rm -r /opt/ttn-gateway/

Thank you for your help!!
