Fix for ticket [b2fa5424e6fcb15]: Better define the format of the sqlite_stat4 file for WITHOUT ROWID tables and make sure the ANALYZE command generates a file in the appropriate format. Use the sqlite_stat4 data to enable the use of WHERE terms that cover all indexed columns plus some prefix of columns in the primary key. check-in: bc2de809 user: drh tags: trunk
