        Creates a new service client

        :param dict config:
            Configuration keys and values as per `SDK and Tool Configuration <https://docs.cloud.oracle.com/Content/API/Concepts/sdkconfig.htm>`__.
            The :py:meth:`~oci.config.from_file` method can be used to load configuration from a file. Alternatively, a ``dict`` can be passed. You can validate_config
            the dict using :py:meth:`~oci.config.validate_config`

        :param str service_endpoint: (optional)
            The endpoint of the service to call using this client. For example ``https://iaas.us-ashburn-1.oraclecloud.com``. If this keyword argument is
            not provided then it will be derived using the region in the config parameter. You should only provide this keyword argument if you have an explicit
            need to specify a service endpoint.

        :param timeout: (optional)
            The connection and read timeouts for the client. The default values are connection timeout 10 seconds and read timeout 60 seconds. This keyword argument can be provided
            as a single float, in which case the value provided is used for both the read and connection timeouts, or as a tuple of two floats. If
            a tuple is provided then the first value is used as the connection timeout and the second value as the read timeout.
        :type timeout: float or tuple(float, float)

        :param signer: (optional)
            The signer to use when signing requests made by the service client. The default is to use a :py:class:`~oci.signer.Signer` based on the values
            provided in the config parameter.

            One use case for this parameter is for `Instance Principals authentication <https://docs.cloud.oracle.com/Content/Identity/Tasks/callingservicesfrominstances.htm>`__
            by passing an instance of :py:class:`~oci.auth.signers.InstancePrincipalsSecurityTokenSigner` as the value for this keyword argument
        :type signer: :py:class:`~oci.signer.AbstractBaseSigner`

        :param obj retry_strategy: (optional)
            A retry strategy to apply to all calls made by this service client (i.e. at the client level). There is no retry strategy applied by default.
            Retry strategies can also be applied at the operation level by passing a ``retry_strategy`` keyword argument as part of calling the operation.
            Any value provided at the operation level will override whatever is specified at the client level.

            This should be one of the strategies available in the :py:mod:`~oci.retry` module. A convenience :py:data:`~oci.retry.DEFAULT_RETRY_STRATEGY`
            is also available. The specifics of the default retry strategy are described `here <https://docs.oracle.com/en-us/iaas/tools/python/latest/sdk_behaviors/retries.html>`__.

        :param obj circuit_breaker_strategy: (optional)
            A circuit breaker strategy to apply to all calls made by this service client (i.e. at the client level).
            This client uses :py:data:`~oci.circuit_breaker.DEFAULT_CIRCUIT_BREAKER_STRATEGY` as default if no circuit breaker strategy is provided.
            The specifics of circuit breaker strategy are described `here <https://docs.oracle.com/en-us/iaas/tools/python/latest/sdk_behaviors/circuit_breakers.html>`__.

        :param function circuit_breaker_callback: (optional)
            Callback function to receive any exceptions triggerred by the circuit breaker.

        :param bool client_level_realm_specific_endpoint_template_enabled: (optional)
            A boolean flag to indicate whether or not this client should be created with realm specific endpoint template enabled or disable. By default, this will be set as None.

        :param allow_control_chars: (optional)
            allow_control_chars is a boolean to indicate whether or not this client should allow control characters in the response object. By default, the client will not
            allow control characters to be in the response object.

            Database system restore parameters.

        :param str if_match: (optional)
            For optimistic concurrency control. In the PUT or DELETE call for a resource, set the `if-match` parameter to the value of the etag from a previous GET or POST response for that resource.
            The resource will be updated or deleted only if the etag you provide matches the resource's current etag value.

        :param str opc_request_id: (optional)
            The client request ID for tracing.

        :param str opc_retry_token: (optional)
            A token that uniquely identifies a request so it can be retried in case of a timeout or
            server error without risk of executing that same action again. Retry tokens expire after 24
            hours, but can be invalidated before then due to conflicting operations. For example, if a resource
            has been deleted and purged from the system, `retrytoken` could be expired or invalidated.

        :param obj retry_strategy: (optional)
            A retry strategy to apply to this specific operation/call. This will override any retry strategy set at the client-level.

            This should be one of the strategies available in the :py:mod:`~oci.retry` module. This operation uses :py:data:`~oci.retry.DEFAULT_RETRY_STRATEGY` as default if no retry strategy is provided.
            The specifics of the default retry strategy are described `here <https://docs.oracle.com/en-us/iaas/tools/python/latest/sdk_behaviors/retries.html>`__.

            To have this operation explicitly not perform any retries, pass an instance of :py:class:`~oci.retry.NoneRetryStrategy`.

        :param bool allow_control_chars: (optional)
            allow_control_chars is a boolean to indicate whether or not this request should allow control characters in the response object.
            By default, the response will not allow control characters in strings

        :return: A :class:`~oci.response.Response` object with data of type None

        :param str db_system_id: (required)
            A unique identifier for the database system.

            A unique identifier for the database instance node.

        :param oci.psql.models.UpdateDbSystemDbInstanceDetails update_db_system_db_instance_details: (required)
            Database instance node update parameters.

        :param str if_match: (optional)
            For optimistic concurrency control. In the PUT or DELETE call for a resource, set the `if-match` parameter to the value of the etag from a previous GET or POST response for that resource.
            The resource will be updated or deleted only if the etag you provide matches the resource's current etag value.

        :param str opc_request_id: (optional)
            The client request ID for tracing.

        :param str opc_retry_token: (optional)
            A token that uniquely identifies a request so it can be retried in case of a timeout or
            server error without risk of executing that same action again. Retry tokens expire after 24
            hours, but can be invalidated before then due to conflicting operations. For example, if a resource
            has been deleted and purged from the system, `retrytoken` could be expired or invalidated.

        :param obj retry_strategy: (optional)
            A retry strategy to apply to this specific operation/call. This will override any retry strategy set at the client-level.

            This should be one of the strategies available in the :py:mod:`~oci.retry` module. This operation uses :py:data:`~oci.retry.DEFAULT_RETRY_STRATEGY` as default if no retry strategy is provided.
            The specifics of the default retry strategy are described `here <https://docs.oracle.com/en-us/iaas/tools/python/latest/sdk_behaviors/retries.html>`__.

            To have this operation explicitly not perform any retries, pass an instance of :py:class:`~oci.retry.NoneRetryStrategy`.

        :param bool allow_control_chars: (optional)
            allow_control_chars is a boolean to indicate whether or not this request should allow control characters in the response object.
            By default, the response will not allow control characters in strings
