        Available in VPC

        Create a read replica server instance to a Cloud DB for PostgreSQL instance.

        Request

        The following describes the request format for the endpoint. The request format is as follows:

        MethodURI
        GET, POST/createCloudPostgresqlReadReplicaInstance

        Request headers

        For headers common to all Cloud DB for PostgreSQL (VPC) APIs, see Cloud DB for PostgreSQL (VPC) request headers.

        Request parameter

        The following describes the parameters.

        FieldTypeRequiredDescription
        regionCodeStringOptionalRegion code
        • Region code of the Cloud DB for PostgreSQL instance for which you want to create a read replica server instance
        • Check through getRegionList
        • First Region of the getRegionList query result (default)
        cloudPostgresqlInstanceNoStringRequiredCloud DB for PostgreSQL instance number
        subnetNoStringConditionalSubnet number of the default network interface to be used in the Cloud DB for PostgreSQL instance
        • Check through getCloudPostgresqlTargetSubnetList
        • Required for a Cloud DB for PostgreSQL instance configured with multi-zone (isMultiZone=true)
        • For a Cloud DB for PostgreSQL instance whose multi-zone is not configured (isMultiZone=false), the subnetNo entry is ignored and it is created in the existing subnetNo
        • Subnet migrations are not available after creating the Cloud DB for PostgreSQL read replica instance
        responseFormatTypeStringOptionalFormat of the response result
        • xml (default) | json

        Request example
