PostgreSQL provides client installation methods for different OSs on its official website.

Procedure

  1. Log in to an ECS.

    1. When you create an ECS, select an OS like CentOS 7 and bind an EIP to it.
    2. Use a remote connection tool to connect to the ECS through the EIP.

  2. Open the client installation page.
  3. Select a DB engine version, OS, and OS architecture, and run the following commands on the ECS to install a PostgreSQL client.
