title: Why pgAdmin copies the existent databases to the new servers?
body: <p>I use pgAdmin 4. pgAdmin comes with a default server named 'postgreSQL 12'. I created my own server or database cluster, but I found out that all the databases in the old server are copied to the new server created by me. By the way, I used the host name 127.0.0.2 and port 5432. How can I prevent copying the old databases to the new server?. One more thing: What is precisely host name/Address. I get stuck with the host name while creating a new cluster because I`m new to SQL. I appreciate if anyone helps me choose a host name.</p>
  <p>Thanks in advance.</p>
