Symptoms

Symptoms are:
- export partition statistics using dbms_stats.export_table_stats for a partition
- drop table and recreate the table with new partitions; afterwords try to import statistics on that specific partition using dbms_stats.import_table_stats
- if the partition in the new table has a new position, no statistics are imported
- statistics table keeps the position of the partition, not the partition name
