 all the in-the-wild corruption examples I have but one.
 
 - During a query, detect when the fts index references a docid
   which doesn't exist in the content table.
 
 - Detect when leavesReaderInit() receives an empty leaf node,

   previously part of an fts table (as if a page from another
   table were re-used).
