Overview
| Comment: | Have the OP_NoConflict opcode set the VdbeCursor.seekResult variable. This speeds up subsequent OP_Insert and OP_IdxInsert opcodes. |

| 19:59 | Reference count the KeyInfo object. Cache a copy of an appropriate KeyInfo for each index in the Index object, and reuse that one copy as much as possible. (check-in: defd5205 user: drh tags: omit-rowid) | |

| 14:52 | Use ansi escape codes to use different colored text for opcode names in the output of [explain_i]: Red for opcodes that insert or delete b-tree elements, blue for opcodes that move cursors and green for the ResultRow opcode. (check-in: 4be2b64b user: dan tags: omit-rowid) | |
