We have imported the tables and data only from a full export dump earlier. Then we are importing the rest of the objects with ANALYZE=N and STATISTICS=NONE in the import parameters but the indexes are still being analyzed.
Immediately following the import, if we query on dba_indexes, the last_analyzed column has a date
which correlates with the date/time of the import.
