- Implementation of the ndb_sync_pending_objects table
- The ndb_sync_pending_objects table contains information about
  metadata objects that have been detected as mismatches by the
  Change Monitor component and are pending synchronization
- The list of objects is retrieved from the sync mechanism every
  time the PFS table is queried by a user
- This information, consisting of schema name, name, and type of
  the object, is sent to the PFS handler
