Internally this method will wait for all current cache operations to finish and prevent new cache operations from being executed. Then checkpoint is initiated to flush all data to disk. Control is returned to the callee when all dirty pages are prepared for checkpoint, but not necessarily flushed to disk.
WAL state can be changed only for persistent caches.
