This topic describes the billing rules for the database proxy of an ApsaraDB RDS for PostgreSQL instance.

Precautions

  • Database proxy instances, read-only RDS instances, and primary RDS instances are separately billed.
  • If the primary RDS instance is locked, the enabled proxy instances are not released but can process only read requests.
