| 17:32 | Multiply all cursor step cost estimates by the estimated size of the row in bytes, in order to get the query planner ot make use of estimated row sizes. This check-in uses magic numbers in a few places (for example, estimates of the size of output rows) and needs lots of refinement. Consider this a proof-of-concept only. (check-in: cb34cfe57c user: drh tags: row-size-est) | |
| 16:53 | Try to remember statistics from ANALYZE using LogEst instead of u64. (Leaf check-in: 8e78557a40 user: drh tags: log-stats) | |
| 10:48 | Merge bug fixes from trunk. (check-in: 1d7b2dc0ea user: drh tags: row-size-est) | |
| 00:36 | Restore the hexrekey pragma which was accidently deleted during the pragma refactoring. Make sure the hexkey and hexrekey pragmas do not overflow buffers with a over-length key. (check-in: 0aca31e151 user: drh tags: trunk) | |
