20:26
Have r-tree prefer to use the constraint "col MATCH ?" over "rowid = ?". <i>drh added later:</i> All changes on this branch have been cherrypicked to trunk and will be merged into sessions from trunk. So this branch can close. Closed-Leaf check-in: b9e45596d8 user: dan tags: sessions-value-dup

02:24
Silently ignore any attempt to add a prefix index for prefixes zero bytes in size to an fts3/4 table. Or any prefix index size so large that it overflows a 32-bit signed integer. Cherrypick [ad4b19d2ac0889a] check-in: 000197cc4e user: drh tags: branch-3.7.11
02:20
