Before this update, binding the data values from a `PerconaXtraDBCluster` custom resource (CR) of the `pxc.percona.com` API did not project the `port` and `database` binding values. Those binding values along with the others already projected are necessary for an application to successfully connect to the database service. With this update, the annotations that the Service Binding Operator uses to expose the binding data values from the backing service CR are now modified to project the additional `port` and `database` binding values. The Service Binding Operator uses these modified annotations to project the complete set of binding values that the application can use to successfully connect to the database service.
