Amazon RDS for PostgreSQL is a PostgreSQL relational database that runs on the Amazon Relational Database Service (RDS).

Supported versions

Create a connection to Amazon RDS for PostgreSQL

To create the connection asset, you need these connection details:

Database name
Hostname or IP address
Port number
Username and password
SSL certificate (if required by the database server)

Select Server proxy to access the Amazon RDS for PostgreSQL data source through a server proxy. Depending on its setup, a server proxy can provide load balancing, increased security, and privacy. The server proxy settings are independent of the authentication credentials and the personal or shared credentials selection. The server proxy settings cannot be stored in a vault.

Proxy hostname or IP address: The proxy URL. For example, https://proxy.example.com.
Server proxy port: The port number to connect to the proxy server. For example, 8080 or 8443.
The Proxy username and Proxy password fields are optional.
