Any reason this isn't at the end of the list?

Also, the comment is wishy-washy.  At this time, the database was recovered but
data was almost certainly lost.  Maybe just say "The database was deleted and
re-opened successfully" or something to that end.

No, no reason. I put up there to be close to INIT_OK.
I moved it to the end, and changed the comment.
Done.

   // Some error, usually I/O related opening the file.
   INIT_FAILURE,
 
   // The database is from a future version of the app and cannot be read.
   INIT_TOO_NEW,
 };
 
 }  // namespace sql
 
 #endif  // SQL_INIT_STATUS_H_
