Azure Private Link support for Azure Database for PostgreSQL is now available in two Azure government regions: US Gov Arizona and US Gov Virginia.
Private Link was recently made generally available for several Azure services in all public clouds. The feature enables you to connect to your PostgreSQL server via a private endpoint. Use it to establish cross-premises access to the private endpoint using ExpressRoute, private peering, or VPN tunneling—or choose to disable all access via a public endpoint.
