| 18:57 | 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.

| 13:32 | Generate complete samples for sqlite_stat4 on WITHOUT ROWID tables. Ticket [b2fa5424e6fcb15b5] (check-in: 8cb43eddab user: drh tags: stat4-without-rowid) | |
