DBMS_STATS.LOCK_PARTITION_STATS does not lock the index statistics when partitions are moved.
Symptoms are as below.
- Index statistics in dba_ind_partitions and dba_ind_statistics become NULL after moving the partition, even when the statistics are locked.
- When there are rows in the table, the index statistics do not become NULL but are regathered during move partition
- The issue occurs only with index statistics. Table statistics remain the same as before the move.
