Connecting to a DB Instance Through pgAdmin

You can use the pgAdmin client to connect to an RDS DB instance.

The pgAdmin version must be 4 or later.


  1. Prepare an ECS or a device that can access RDS DB instances.

    To connect to a DB instance through a floating IP address, you must:

    • Create and log in to an ECS. For details, see Purchasing an ECS and Logging In to an ECS.
    • Ensure that the ECS and DB instance must be in the same VPC.
    • Ensure that the ECS must be allowed by the security group to access RDS DB instances.
    To connect to a DB instance through an EIP, you must:
    1. Bind the EIP to the DB instance. For details, see Binding and Unbinding an EIP.
    2. Ensure that the local device can access the EIP that has been bound to the DB instance.
  2. Install the pgAdmin client on the prepared ECS or device.


  1. Start pgAdmin.
  2. In the displayed login window, choose Servers > Create > Server.
