Patching this database is not an option, at least now (big customer, production database and so on)
But we have other customers with 9206 on the same platform. I'll check next week how are their index statistics. I did a quick check now but they don't seem to have the same problem. They haven't compiled that specific table. They do have num_rows=0 etc in the user_indexes statistics but for tables that are actually empty (i checked only some. I'd need to write a script to check every table/index couple).
On Metalink I haven't found anything about this, so I don't think about a bug here. Certainly I am missing something but .. what ??
